Temperature data-logger Kaye ValProbe ® RT

for temperature traceabilityfor freezerfor pharmaceutical products

Description
The Kaye ValProbe RT rigid-sensor data logger is a temperature monitoring device for validation and process control in sterile and temperature-controlled environments. It integrates a precision platinum RTD sensor with a rigid probe design to measure from -85°C to +140°C and is engineered for applications such as sterilizer qualification, stability chambers and lyophilization processes.

Key features

• Measurement range (complete logger): -85°C to 140°C
• Single precision RTD sensor, rigid probe
• Probe lengths available: 1.5, 3, 6, 9 in (38, 76, 152, 229 mm)
• Probe tip diameter: 3 mm (0.118 in)
• Operator-programmable sampling starting at 1 second; up to 100,000 data points stored
• Antenna diversity for robust RF communications

Applications

• Steam sterilizer validation
• Dry heat sterilizer monitoring
• Steam-in-place (SIP) process control
• Water cascade / autoclave qualification
• Incubator and stability chamber monitoring
• Freezers and cold-chain validation
• Freeze-drying / lyophilization process monitoring
• Vessel and bioprocess temperature mapping
