The Isotech B8 30 130 Cell is small enough to fit into portable Dry Blocks such as the Venus and Europa models. For the larger blocks like the…

The ITS-90 specifies the SPRT to the freezing point of silver, 961.78°C. Thermocouples can be used beyond this temperature but it is difficult to see…

The 670SQ is our latest thermometer, to be specifically designed to give optimum performance up to the aluminium point. Its construction permits the…

This economically-priced Standard Platinum Resistance Thermometer, Model 909, is the workhorse of calibration laboratories all over the world. During…

This bath is the result of many years of development and is used to maintain the temperature of standard resistors used with thermometry bridges. It…

Eventually all resistance thermometry refers back to one or more fixed resistors. These are a key element in any laboratory which measures…

By temperature controlling an otherwise very stable resistor a performance close to the very best available World-wide can be achieved at a…

The TRU 937 (Temperature Reference Unit) supplies a stable and accurate 0°C or elevated Reference Temperatures between 45°C and 70°C. It is a…

The TRU (Thermocouple Reference Unit) supplies a stable and accurate 0°C, or elevated reference temperature. It is a self-contained all solid-state…


The TRUrac is a 0°C or elevated temperature thermocouple reference system mounted in a 19” chassis. It has been developed for situations where…
