High-temperature calibration bath CTR-25

low-temperatureportable

Description
The Kaye CTR-25 is a portable liquid calibration bath designed for on-site and laboratory verification of temperature sensors and data loggers in GxP and industrial environments. It supports efficient verification of up to 10 ValProbe or ValProbe RT loggers and accommodates various process probes. Onboard firmware enables automatic real-time checks with ValProbe RT or manual verifications with standard ValProbe units.

Key features

• Stability: 0.01 °C; typical uniformity: 0.02 °C
• Fast heating and cooling performance
• Verification for up to 10 rigid ValProbe/ValProbe RT loggers and other data loggers
• Fixture holds 10 loggers plus one IRTD reference
• Portable design, ~20 kg for field use and shipping
• Peltier temperature control (compressor-free)
• Stainless steel casing resistant to sterilizing chemicals
• Universal power supply 110/240 VAC, 50/60 Hz and large front display

Applications

• Steam-in-Place (SIP) checks: 122 °C to 140 °C
