2014/10 EYC-TECH " executes international standards, IEC61298 & ISO17025, to inspect product accuracy and capacities"
Quality ─ Specific / Professional / Stable
We, EYC-TECH, according to IEC61298 executes to inspect accuracy and capacity of product by ISO17025 temperature & humidity calibration laboratory.
Inspect capacity way ─ IEC 61298
Under specified conditions, when according to the rules of procedure testing the device, the max positive and negative deviation of specified curve were observed.
The algebraic difference is between measured value and true value of the measured variable.
3. Maximum measured error
Max positive or negative deviation of upstream or downstream on per measuring point.
A device or instrument according to the orientation sequence of input which is exerted giving corresponding the characteristics of different output.
Under the same working conditions, when using the same input value from the one direction to do whole range moving, in a short period of time, doing many times continuous measurement on the output value to take the algebraic differences between limit values.
Execute Standards ─ Temperature & Humidity Calibration Laboratory (ISO 17025)
♦ Cooperation with national-level " Center for Measurement Standard"
♦ ISO 17025 calibration level
♦ Pecision calibration equipments
♦ Service:Calibration and resell equipment
《Laboratory Calibration Range》

♦ Dew / Frost point From-80~+20℃
♦ Relative Humidity From 10~95%RH
《Humidity Inspection Calibration System》
♦ Thunder2500 humidity Generator >> Temperature:-10~70℃, RH:10~95%
♦ MBW473 Dew point Mirror >> Temperature:-20~80℃, RH:5~100%
Capacity Inspection - Measuring curve chart, max. nonrepeatability, hysteresis error
♦ Samples quantities : 5 EYC THS34/35 temperature & humidity transmitters
♦ Temperature Conditions : 25℃、10℃、40℃、25℃
♦ Humidity Circulation : 20%、40%、60%、80%、90%、80%、60%、40%、20%
♦ Executing way : Execute every temperature condition 3 times humidity circulations.
According to Measuring curve chart, max. nonrepeatability, hysteresis error of testing samples,
the deviation value range is lowest. The result represents specific and stable of profuct.
