High-temperature dry block heater Gemini 700 LRI

digitalwith thermostat

Overview
The Gemini 700 LRI is a portable calibration furnace for temperature probes covering 50°C to 700°C. Its large calibration volume allows simultaneous calibration of multiple thermometers, thermocouples, resistance probes, thermostats and other sensors. It is particularly suited for calibrating large-diameter probes thanks to a 65 x 160 mm insert.

Removable insert
The standard removable insert features 8 holes of Ø 8 mm with a depth of 154 mm. Insert suitable for large-diameter probes (insert 65 x 160 mm).

Versions

• Model B (Basic): equipped with a controller displaying setpoint and the temperature measured by the control probe simultaneously.
• Model S (On-Site): in addition to the Model B features, includes a digital indicator to which a reference probe can be connected for improved accuracy; eliminates temperature gradient and loading errors.

Usage advice
For laboratory use, it is recommended to connect the Gemini 700 LRI to a high-performance temperature indicator.
