The silicon semiconductor temperature sensor project, which is the core technology of our company, has obtained a free subsidization of 1 million RMB from innovation fund for small technology-based firms of Ministry of Science and Technology in 2005. Heartfelt thanks for the support of government to technology innovation of small firms.

JM111I intelligent portable thermo-hygrometer has finished the prototype design.
It features:
  1. Brand-new outer shell design
  2. Celsius or Fahrenheit selectable, digital hold function
  3. First use the plan of power supply of one 1.5V AA battery, operating current less than 4 mA
  4. Brand-new humidity sensor, temperature compensation and signal conversion circuit, abandoned bad anti-static HIH3610 humidity sensor of Honeywell, solved the problem of leading damages by static radically.

JM0101 humidity standard generator, which was researched and developed by our company, has acquired the National Patent. Humidity standard generator is large instrument project strongly recommended by our country for many years to research and develop. As we know, there is no report about successfully making this generator by others until now.

The stability and humidity generated accuracy is ±0.5%RH——better than the one of 2500 humidity generator of Thunder Sientific company with ±1.0%RH (600,000 RMB), and SRH-1RC 135ADR of Shinyei company with ±1.0%RH (500,000 RMB).

JM0101 works in unilateral opening style, without seal, may calibrate continuously and generate several standard points simultaneously. That’s what other generators can not achieve

JM800IM universal-input controller was produced in December, which has many bright characteristics, reflects a new level of independently developing and designing digital intelligent meters, and further enhanced the whole matching abilities of JM products.

New product JM6200I
In June, 2007, our company successfully developed high-precision intelligent digital thermometer. As the best portable digital thermometer on the domestic market at present, its accuracy is ±0.05% and resolution is 0.01℃/0.02℉ at wide temperature range -199.99~400.00℃/-327.98~752.00℉.
JM6200I is mainly applied to precise measurement.
