General Description

TN1 series products are extra compact size infrared thermometer fitted well in the pocket.
Large LCD display and easy to use interface make this thermometer become the most useful tool in checking temperature.
Within one second, no more waiting for minutes as traditional contact type thermometer does.

Typical Error of Reading

A typical error of reading is not a simple figure, it's a function of Tobj (object temperature) & Tamb (ambient temperature)
Because Infrared Thermometer is a "Relative" measurement instrument. (It compares the Tobj against Tamb)
So, the error has a minimum value when Tobj ~ Tamb,
that is when you measure something close to ambient temperature.
For ZyTemp, this minimum value (dTabs) = 0.15°C / 0.27°F ,
usually, our competitor is larger than 0.2°C / 0.36°F
At higher or lower temperature, there is a Gain Error, usually 2%.
Q: Since the spec is "+/-2°C or 2%", is IRT most accurate at Tobj=0°C?
A: No, as described above, IRT use a "Relative" measurement, IRT is most accurate at Tobj=Tamb,
In other words, when you point the IRT at a "near room temp" object, it will be very accurate.

Q: Can I calibrate my IRT by pointing it to a wall (25°C)?
A: No, even though the Gain run away, the IRT still shows 25°C, you have to use a "Temperature Different From Tamb",
(ex. 0°C or 50°C)? 0°C is the most available temperature "standard", for ordinary user.

Certificate of Calibration

Founded in July 2000, ZyTemp belongs to world-class Infrared Technology-oriented thermometer manufacturer - Radiant Innovation Inc. and become a premier provider of infrared temperature measurement devices.
