Review on 🌡️ Bosch-style Line 2" Mechanical Water/Oil Temperature Gauge - Actron SP0F000053 (Black Dial Face, Black Bezel) by Kartik Starks

Fortunately tested before installation - Suspended transmitter unit in a pot of boiling water where my laser temp gauge (and meat thermometer) read about 215 degrees, this gauge read 200 - 202 Waited about 3-5 minutes for stabilization (quickly stabilized). Checked three times, same result each time. A deviation of 10-12 degrees from the actual temperature is far from accurate, especially at the boiling point of the liquid.
