Review on 🌡️ TPI 312C Penetration Thermometer - Certified Calibration for Accurate Measurements by Brandon Vox

I have been using two digital thermometers of this make/model in my home inspection business for the past eight years. Super reliable. The plastic over the buttons has worn away, but each thermometer still works perfectly. They are easy to calibrate and hold that calibration very well. Yes, they look in the tooth a little long. After all, they have fallen onto the concrete floor countless times. And recently, when changing the battery, one of the battery covers cracked. Replaced it with a broken smaller brand case and I'm back in business. No complaints.
