PTC®'s Time Track Recording Thermometer permanently records temperature versus time with both accuracy and reliability.
These portable, self-contained units feature a bi-metallic sensing element and mechanical clock movement for the ultimate in reliability. The redesigned scriber and inkless charts produce an easy to handle and store permanent record.
The model 616 is intrinsically safe and was designed for monitoring environmental and processing conditions of temperature-sensitive commodities. Monitoring and recording temperature readings are essential to maintaining the safety and quality of perishable and temperature sensitive products such as food products, chemicals, pharmaceuticals, blood, floral, ammunition, etc. 100 charts are included with the purchase of a 616 Time Track Recorder.
This thermometer uses a spring-wound chart drive and will operate in extreme temperatures (from -40°F to +240°F) where batteries fail. One full winding is enough to drive the chart well beyond its full recording range.
