Product Overview
Ensure the absolute safety of your critical refrigerated inventory with the AVTECH Digital Fluid Temperature Sensor. Designed specifically for extreme cold storage environments, this sensor tracks the temperature of fluids and refrigerated items directly, rather than simply measuring the air temperature inside the cooling unit. By feeding real-time data back to your Room Alert monitor, it enables continuous data logging and automatic corrective actions to prevent the loss of sensitive specimens or perishables.
Specialized Propylene Glycol Housing
Each temperature probe is completely encased in a sealed tube containing Propylene Glycol. This colorless, non-conductive liquid features extremely low freezing and high boiling points, perfectly simulating the temperature of liquid assets. This makes it an essential tool for laboratories monitoring vaccines, IV bags, and plasma, as well as facilities managing aquariums or specialized refrigeration devices.
Plug & Play Deployment
Installation is simple and immediate. The sensor plugs directly into any standard RJ-11 digital sensor port on a compatible Room Alert monitor, requiring no complex wiring setups.
Important Lifespan Consideration
Please note: Because propylene glycol naturally and gradually breaks down the sensor element’s internal silicone coating over time, the operational lifespan of this specific sensor is generally limited to approximately one year.
