The Fast Response (FR) Thermapen pocket thermometers are "probably" the fastest reading contact thermometers on the market today. The true temperature of a product can be tested in less than five seconds.
The response time of any thermometer is dependant on two main factors, the mass of the sensing tip of the probe and the rate of heat transfer from the product to the sensor. The latter is dependant on many factors, the most important being the state of the substance being measured. With both air and liquid, agitation is crucial to rapid response. The ETI Calibration Laboratory has tested the FR Thermapen in a stirred water bath with amazing results. Each FR Thermapen reached 100% of the test temperature in less than five seconds.
The FR Thermapen utilises tried and tested electronic circuitry designed for reliability and ease of use. The thermometer incorporates a clear digital display with a precise read-out of temperature over the range of -49.9 to +199.9°C or -50 to +300°C and a 0.1°C or 1°C resolution. Both "Low Battery" and "Open Circuit" indication are also displayed when applicable.
The FR Thermapen is powered by a 12 volt MN21 alkaline battery with a minimum expectancy of 150 hours.
