    ETI ThermaGuard® 101 Fridge/Freezer Thermometer

    The ETI ThermaGuard® 101 Fridge/Freezer Thermometer measures the air temperature in cold storage units via two sensors: an internal sensor and an external remote probe on a 1m PVC lead. The probe can be mounted to a fridge wall whilst the internal sensor is ideal for measuring room temperature. It has a measurement range of -39.9˚C to 49.9˚C via the external sensor and -19.9˚C to 49.9˚C via the internal sensor. Accuracy stands at ±0.4˚C and readings are given with a resolution of 0.1˚C.

    The ETI ThermaGuard 101’s clear LCD screen displays minimum, maximum and current readings from either sensor and it is easy to adjust the settings via the three simple push buttons. It is possible to set audible alarms for when temperature falls outside user-adjustable limits and the screen will also flash when alarms are triggered. A CalCheck feature at 0.0˚C allows the user to verify the thermometer’s performance.

    Splashproof ABS casing (IP54-rated) makes the ETI ThermaGuard 101 extremely sturdy and a silver Biomaster additive helps prevent microbial growth for greater hygiene. Two AA batteries have an expected life of three years and can be mounted on a fridge wall with the supplied ABS plastic probe mounting bracket. A UKAS calibration certificate can be added to the purchase by clicking the checkbox above.
