1 x Digital LCD Thermometer
2 x LR44 button battery

Temperature error: plus or minus 1 degree at room temperature

NOTE: This product is its small size, easy to use, measuring the temperature suitable for general use, such as temperature accuracy stringent requirements to buy with caution. The thermometer is erroneous, at room temperature within 2 degrees, but the larger error is at a high temperature, the water in the environment, only to about 94 degrees measured! High precision is required, do not shoot!

 

Thermometer common sense:

 

1. thermometer which shows the speed and the length of the line does not have any relationship, only the internal circuit board and the chip-related

 

2. Alternatively thermometer sensor line length: 1 m (1M) and 2 m (2M)

 

3. The thermometer is divided into two seconds refresh rate (2S) and 10 seconds (10S) . The so-called refresh rate is reflected in the speed of said thermometer, digital temperature change speed. That reflects the fast 2 seconds, 10 seconds to reflect slower. Thermometer default is 10 seconds. Moreover, because 2S fast refresh rate, also with respect to 10 seconds for more power, so that customers buy 2 seconds later point recommended spare battery . Theoretically 10 seconds of two batteries can be used for 25 months, then you can use 2 seconds five months, this is only a theoretical value. Actual power consumption will also be affected by dryness temperature and other environmental factors. 10S will generally use more than one year.
