Doric 450-TH Thermistor Thermometer
Connects Directly to 400 Series Probes (Except
Dsposable)
The Doric 450 Series
digital thermometers are among the most accurate, reliable, and convenient
handheld instruments ever developed. Using a unique, patented noise reduction
circuit, the Series 450 achieves the high repeatability and accuracy of many line-powered bench top units
in a handheld instrument.
A custom-designed dual integrated
circuit set gives you a single instrument with wider temperature ranges, higher
resolutions, and longer performance than most other handheld thermometers. Data hold
freezes the displayed reading for easy viewing away from difficult measurement
locations.
Battery life is unsurpassed, with a single 9V battery providing more than 1200 hours of use. An externally available zero pot, conveniently located at the back of the instrument, lets you match ice point calibrations to specific probes for even greater system accuracy.
The 450-TH is compatible with YSI 2252Ω B curve thermistors. The input is a standard 1/4" phone plug.
The 450 is also available in
Thermocouple, RTD, and Thermistor configurations. Please specify when ordering.

Hart Scientific 1521 and 1522 Ultra Precision Handheld Thermometers
Requires Connector Change for 400 Series Probes
The
Hart Scientific Series of Thermistor Thermometers provide laboratory accuracy in
a convenient handheld format. With the Super-Thermometer, Black Stack, and
Tweener thermometers, Hart established itself as the clear product leader for
thermometer readouts. Our pattern of offering more power and more versatility
for less money is indisputable. Hart offers the two most powerful handheld
thermometers in the world.
The Models 1521 and 1522 are the first standards thermometers to fit into a battery-powered handheld package. They’re as accurate as ±0.005°C! Fitting easily into your hand and weighing only 1 pound (0.4 kg), these thermometers can go anywhere. And when they get there, you can have total confidence in the accuracy of your measurements. The 1522 adds the power of a full data logger, with memory to hold 10,000 readings.
Ultra-stable thermistors offer excellent stability and even greater accuracies over a more narrow range—typically from about –10°C to 110°C. At temperatures below 50°C, these Handheld Thermometers read thermistors to ±0.005°C. Accuracy at 100°C is ±0.02°C. While a small number of handheld thermometers on the market offer 0.01° resolution, they fail to provide the accuracy necessary for the last digit to be meaningful. Hart’s Handheld Thermometers let you select resolution from 0.1° to 0.001° and offer the accuracy to support even 0.001° resolution.
Probes attach to the 1521 and 1522 using Hart’s own “INFO-CON” connector. The INFO-CON (partially based on U.S. Patent 5,857,777) allows you to change the probes you use without requiring you to reprogram your readout. A memory chip in the INFO-CON stores all the critical information about your probe, including its serial number, recall date, and calibration constants.
Doric 600 Series Thermistor Thermometer

Hart Scientific 1504
Resolution to 0.0001°
Requires Connector Change for 400 Series Probes
One of Hart’s best-selling products is the Tweener thermometer, and there’s a reason. No other company, not one, has a thermometer that comes close to the performance and features of the Tweener for anywhere near its price.
The Model 1504 features accuracy up to ±0.003°C with a resolution of 0.0001°C. It also has an optional battery pack for completely portable operation.
Each Tweener is programmable to match any probe’s constants for maximum linearity and accuracy. All probe constants and coefficients are programmed through simple, front-panel keystrokes. Temperature is displayed in °C, °F, K, or resistance in ohms.
Each thermometer comes complete with an RS-232 interface for automation of temperature data collection, calibrations, or process control functions. An IEEE-488 interface is available as an option.
The 1504 is calibrated digitally using the front-panel buttons. You never have to open the box to calibrate it. This calibration protocol further reduces the cost. It goes where you go and works the way you want it to.
Software
With our Model 9934 LogWare, Tweener models may be used for real-time data acquisition. Collect data and analyze it graphically or statistically. Additionally, Tweeners may be used as reference thermometers with our MET/TEMP II software.
4 Channel
Thermometer
Specifications Pricing
Requires Connector Change for 400 Series Probes
Four
channels for PRTs, thermistors, and thermocouples
Displays eight user-selected data fields from any
channel. Logs up to 8,000 readings with date and time stamps.
Battery provides eight hours of continuous operation.
Hart’s Model 1529 Chub-E4 Thermometer gives you four channels, three major sensor types, lab-quality accuracy, and a ton of great features, all at a price you’ll love.
Inputs
The Chub-E4 has four inputs for reading four different sensors simultaneously, and we’ll configure those inputs in any of three different ways according to your preference. Choose four channels of thermocouple inputs, four channels of PRT/thermistor inputs, or two channels of each. With this thermometer, reading thermocouples, PRTs, and thermistors accurately from the same device is no problem.
Thermistor readings are converted using the Steinhart-Hart polynomial or standard YSI-400 curve and are as accurate as ±0.0025°C at 25°C with resolution of 0.0001°
PRTs and thermistors connect easily to the 1529 using Hart’s patented mini DWF connectors, which accept bare wire, spade lug, or mini banana plug terminations. Thermocouples connect using standard or miniature terminations. Measurements are taken each second and can be taken simultaneously or sequentially. A special high-speed mode allows measurements on one channel to be taken at the rate of 10 per second.
Display
If you think three sensor types and four inputs sounds versatile, wait until you see the display panel on the Chub-E4. Displaying measurements in °C, °F, K, ohms, or millivolts and choosing temperature resolution from 0.01 to 0.0001 are just the beginning.
You can also select any eight items from our long list of displayable data fields to view on-screen. Choose statistical functions such as averages, standard deviations, and spreads; choose probe information such as probe type and serial number; choose T1-T2 functions using inputs from any two channels; or choose utility functions such as the date, time, and battery power level. You can even save up to 10 screen configurations for easy recall.
The push of a single front-panel button also brings up a simple menu system to easily guide you through all the internal setup and memory options of the 1529. Probe coefficients, sample intervals, communication settings, password settings, and a host of other functions are all easily accessible.
Communications
The memory and communications capabilities of the Chub-E4 make it perfect for benchtop thermometry, on-site measurements, lab calibration work, and remote data logging. Optional software packages from Hart make this one of the most powerful thermometers on the market.
With battery power and memory to store up to 8,000 measurements (including date and time stamps) at user-selected intervals, the 1529 has plenty of data logging capability. Store 100 individual measurements or any number of automatic log sessions (up to 8,000 readings), each tagged with an identifying session label. Fourteen different logging intervals may be selected, from 0.1 second to 60 minutes.
With Hart’s 9935 LogWare II, data may be quickly downloaded to your PC for complete graphical and statistical analysis. Separate log sessions may even be automatically downloaded to separate files based on session labels. With this software, the 1529 can even be used for real-time data logging. Log four channels at once directly to your PC with virtually no limit to the number of data points you take. You can analyze data, set alarm events, and even set delayed start and stop times.
With MET/TEMP II software, the Chub-E4 may be integrated into a completely automated calibration system. Use one input for your reference thermometer and calibrate up to three other thermometers automatically. An RS-232 port is standard on every unit. An IEEE-488 port is optional.
