Description
Greisinger GMH 3710
The Greisinger GMH 3710 is a high-precision digital thermometer designed for use with Pt100 resistance temperature detectors (RTDs). It’s known for its accuracy and resolution, making it suitable for applications like calibration laboratories, quality assurance, and industrial processes. The device measures temperatures from -199.99 to +850°C with a resolution of 0.01°C and an accuracy of ±0.03°C.
Here’s a more detailed breakdown of its features:
Key Features:
- Measurement Input: The GMH 3710 uses Pt100, 4-wire probes with a 4-pin mini-DIN connector.
- Temperature Range: It can measure temperatures from -199.99 to +199.99 °C or -200.0 to +850.0 °C.
- High Accuracy: The device boasts an accuracy of ±0.03°C at the 0.01°C resolution setting.
- Resolution: Offers a resolution of 0.01°C or 0.1°C, depending on the selected range.
- Analog Output: Includes a freely adjustable analog output (0-1V).
- Offset and Slope Adjustment: Allows for manual offset and slope correction to fine-tune measurements.
- Min/Max Memory & Hold Function: Features min/max value memory and a hold function to capture extreme and stable readings.
- Interface: Can be connected to a PC via a serial interface (requires optional interface converter).
- Power Supply: Powered by a 9V battery or an optional 10.5-12V DC power supply.
- Accessories: Sold without probes or other accessories, but compatible with various Pt100 probes and optional accessories like a carrying case, interface converter, and operating software.
The Greisinger GMH 3750 is the big brother to the GMH 3710, so if you want the ultimate hand held reference thermometer, take a good look at this product!

The GMH 3750 still has all the same benefits as the GMH 3710 but with the added feature of datalogging so you can record those measurements and down load them later to your PC. Just push the record button and the current temperature reading being displayed with be stored internally. 99 Data sets can be recorded.
Custom Curve fit is the next other cool difference between the two units, this allows us to use the GMHKonfig software to calculate new coefficients and upload them to the 3750, this allows the probe and 3750 to pretty much match our reference probes across the calibrated range. The GMH 3750 is now well within its accuracy specification.
Just like the 3710 you have a selection of PT 100 4 wire probes to choose from. There are probes with a protection sheath to give you even higher accuracy and high shock resistance. Or even a insertion probe to push into soft media.
Each 3750 can be supplied as a calibrated system, complete with our own IANZ endorsed calibration certificate.
So if you want a good quality reference thermometer then look no further, this is the one for you.

Technical Specifications
Technical Specifications
Supported probes Pt100 4-wires (2-wire possible)
10.1 4-wire connections
The device is constructed and optimised for the connection of a Pt100 4-wire probe via 4 pole Mini-Din
connectors.
4-wire connection
Figure shows upon probe jack pins
10.2 2- or 3-wire connections
It is also possible to connect an 3- or 2-wire probe to the device. Please observe that in consequence of the
cable and contact resistance an increased measuring fault will occur.
The connection of these probes should be carried out as follows:
