SDW electronic thermometer manual SDW series digital point Wenyi, is the latest temperature measuring instruments, imported large scale integrated circuit chips and high-precision temperature sensing element, it has a high degree of immunity to interference, stability and reliability , LCD liquid crystal digital display reading is clear, accurate, low power consumption, fast response time. Our products Warranty Where the quality of, and responsible for the free repair within six months, except (sensor) after the expiration of damage, cost charge a fee. Instrument should pay attention to the use of the instrument temperature range, such as over-temperature caused by the use of the sensor is damaged, shall be the responsibility of the user. * Note 1. Use digital instability and measurement uncertainty is too large, check: laminated battery voltage, operating voltage (power measurement) if drops to 7.5V LOBAT words should be re- Note replace the battery, replace the battery polarity. (2) where there is a fixed value (heating, digital does not change), check: sensor socket is bad, wiring for breaks, pay attention to the polarity when wiring. This instrument applies to the measurement of gases, liquids, cold storage and steam temperature of the medium, especially for social central heating unit, the indoor temperature. * Technical parameters * (1) Measuring range: -50-150 ° C (2) Resolution: 0.1 ° C (3) Temperature measurement accuracy: ± 0.5% (4) power supply: DC 9V (laminated battery) ( 5) Sampling rate: 3 times / S (6) Power consumption: less than 0.01W
