Solid-state sensor probe eliminates mercury contamination

Thermometer 89094-770 has a sensor probe that is sealed in a 2.5x6.4 cm (1x2¹/₂") bottle filled with GRAS nontoxic glycol. The solution insulates the sensor from rapid temperature changes, such as when refrigerator door is opened. Thermometer 89094-768 has a plain 5mmx1.9 cm (³/₁₆x ³/₄")sensor probe. Thermometer 89094-772 has a sensor probe that is sealed in a 5 mL bottle filled with GRAS nontoxic glycol. The bottle mimics vaccine temperature and fits in a vaccine tray.

Thermometers fulfill all CDC thermometer and vaccine thermometer requirements. A serial numbered certificate is provided from an ISO 17025 calibration laboratory accredited by A2LA to indicate instrument traceability to standards provided by the National Institute of Standards and Technology.

Display case is made of high-impact, chemical-resistant ABS plastic. Jumbo 3.8 cm (1¹/₂") digits are readable from 9m (30'). Display simultaneously shows maximum, minimum, and current temperatures. Alarm feature provides an alert when temperature rises above or falls below a programmable set point. Sensor and 3m (10') micro-cable continue to perform accurately when submerged in water. Micro-cable permits refrigerator and freezer doors to close on it without affecting the seal.
