F100 High Precision Thermometer F100 Digital Thermometer The PSL Rheotek - F100 precision thermometer is suitable for very accurate temperature 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 liquid 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 Calibration - 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 viscometer bath to be checked at different depths. The long probes also meet the minimum immersion depths required by viscosity test methods. ● Key features Large LCD display Robust handset Single or dual probes System calibration Re-chargeable battery F100/C High stability F100/B/CAL-4T ASTM D445 compliance www.psl-rheotek.com Poulten Selfe & Lee © 2014 F100 Specifications & Models F100 Specifications Temperature range (°C, °F) -50 to +250°C Resolution 0.001°C Stability < 0.005°C per year Test Method Compliance ASTM D445 (kinematic viscosity) System calibration accuracy 0.015°C or better Probe input 2 x DIN sockets with screw lock for PT100 Resistance probes Handset dimensions 232mm x 97mm x 53mm Weight 500g (1.1lbs) PT100 probe dimensions Length 350mm x OD 6mm The requirement in ASTM D445 for DCT (Digital Contact Thermometers) is for a minimum accuracy (uncertainly) of 0.02°C for display (indicator) and sensor combined.
