Review on ๐ก๏ธ Control Traceable 4648 Jumbo Display Vaccine Thermometer: Accurate Readings from -50ยฐC to 70ยฐC (-58ยฐF to 158ยฐF) Range, with 0.1ยฐ Resolution by James Trapkin
Well, when it works, false alarms are common.
Often shows error "LL.Lโ which means there are problems reading the sensor. It usually clears up within a minute or two, it's very frustrating to turn off the alarm. I have no idea if the device or the probe is causing the problem. Update 01/29/2018: I often fail to register the probe at all, stuck in the LL.L error. The thing is now practically useless.
- Easy to use
- Long delivery time
