Pressure data-logger ValProbe RT

temperaturefor temperature traceabilitysterilization

Description
The Kaye ValProbe RT pressure and temperature data logger combines RTD temperature sensing and an absolute pressure sensor in a single compact unit. It measures temperature from 0°C to 140°C and absolute pressure up to 5 bar with 1 mbar resolution. The electronic design and field-replaceable 3.6 V lithium battery support extended deployments. Antenna diversity improves RF communication reliability.

Key features

• Temperature range (complete logger): 0°C to 140°C
• Pressure range: 0 to 5 bar absolute, 1 mbar resolution
• Connection fitting: 1/4 NPT

Applications

• Steam sterilizers / autoclaves
• Steam in Place (SIP) processes
• Water cascade / fall sterilizers
• Process and storage vessels
