F100 High Precision Thermometer F100 Digital Thermometer

The PSL Rheotek - F100 precision thermometer is suitable for very accurate measurement with high long term stability. The F100 is recommended to be used as a reference thermometer for all viscosity applications, as well as other baths.

The F100 consists of two models: - handset with one PT100 resistance probe - handset with two PT100 resistance probes.

User functions include – display hold, display zero, one time measurement log, statistical analysis – min/max, average and standard deviation. A USB socket provides external communication to a PC for logging purposes. A Nickel-Metal Hydride (NI-MH) rechargeable battery is supplied with a charging socket built into the handset together with low battery indicator.

F100/A/CAL-4T - to meet ASTM D445 accuracy requirements, a resistance calibration followed by a temperature calibration at key kinematic viscosity set-points is carried out on the combined handset and probe system.

The F100 probes are 335mm long enabling a bath to be checked at different depths. The long probes also meet the minimum immersion depths required by viscosity test methods.

* Additional calibration points below

Annual recalibration of the F100 handset and probe(s) is recommended. The as found re-calibration will take into account any drift that may have arisen whilst the F100 has been in use.
