• SPRTs (Standard Platinum Resistance Thermometers) are high-precision temperature sensors that utilize the predictable change in electrical resistance of platinum with temperature.

• The resistance element is of pure platinum, coiled and mounted in a strain free construction.

• Three thermometer lengths are available, standard length 480mm, extra length 550mm or maximum length 600mm. 

• The most popular of the special thermocouples Isotech makes for researchers

• All wires are 99.999+% pure and are fully annealed according to the recommendations of McLaren.

• Temperature range: 0°C to 1000°C

• Uncertainty: 0-400°C ±0.07°C. 400-1000°C ±0.05°C

• Gold & Platinum Purity: 99.999% pure

• Many other models available - please ask!

• A thermometry bridge is a device used in temperature measurement to compare the resistance of a temperature sensor with a known reference resistor at a given temperature

• The instruments use a completely new measurement technique to achieve accuracies better than 0.02 parts per million (ppm).

• The microK range consists of four instruments offering a choice of measurement accuracy of 0.07 to 0.5ppm over the whole range, equivalent to 0.07mK to 0.5mK over the whole range of an SPRT with a Ro >2.5Ω. 

• Calibrate thermometry bridges quickly, simply and in-house

• The RBC (Resistance Bridge Combinator) utilizes a network of four stable four-terminal resistors that can be arranged in 35 series and parallel combinations

• ​By measuring these combinations in two ways, up to 70 measurements can be taken. With just four unknown resistance values, up to 66 independent measurements can reveal errors in bridge readings.

Unit Shown: milliK Precision Thermometer​

• This unit sets anew accuracy standard for measuring and calibrating a wide range of temperature sensors spanning from -270°C to 1820°C.

• The milliK has two input channels for sensors and a third channel for current. It can be expanded to become a measuring system with up to 33 channels reading SPRTs, RTDs, Thermistors, or Thermocouples with the option to control calibration baths and log readings accurately
