Single Point Push-Button Calibration:
The meter with single point calibration function, it is permitted to use standard conductivity solution, you need only set conductivity value of the calibration solution at 25℃ and immerse conductivity electrode into solution, then press ENTER key, the meter will be calibrated automatically.
Auto Standard Solution Recognition:
In calibration, the meter will display ERROR if you use conductivity solution by mistake.
Auto-Ranging for Conductivity:
The meter with auto-ranging function when measure conductivity or total dissolved solid. After electrode immersed in solution, CD5 series will fast response and convert range.
Auto Temperature Compensation:
The meter will recognize the temperature sensor automatically and measure temperature after temperature sensor connected to the host. If the conductivity electrode connected to it, the meter will enter automatic temperature compensation.
Adjustable Temperature Coefficient:
Solution contained different ions usually have different temperature coefficient,CD5 series can be set in the range of 0 and 3.9% per centigrade degree.

Adjustable Cell Constant:
When measure solution with higher or lower concentration, you should choose different constant of conductivity electrode. The meter with three cell constants for your choose, it can save the measured value for different constant electrode separately. After setting the constant, you needn't calibrate it again when replacing a new electrode.
Adjustable TDS Coefficient:
According to the theory of electrical conductivity, you need estimate TDS coefficient when measure total dissolved solid of solution.CD530/540 can be set in the range of 0.01 to 1.00,
which can ensure accuracy of measured value.

Clean Tap Monitor CT-1                                   
The clean tap monitor automatically monitors the quality of a filtration system directly from the base of any standard faucet. The unit provides an indicator through three LED light.
Three-part monitor process:
1. Monitor Processor: By measuring the volume of water passing through the filtration system by the electric program, the Monitor Processor sends the signals to the LED lamps or the buzzer and indicates whether the filters are functioning normally, approaching capacity or past useful capacity.
2. Flow Switch: The Flow Switch senses the dispensed water and sends the signals to the Monitor Processor.
3. Monitor: One of the three-colored LED Lamps blinks for a 3-6 seconds every time water is dispensed. Green Light indicates the normal function of filters, Yellow Light, the readiness to change, and Red Light, the need of immediate change.
Green Light: Filter Usage = 0% - 80%
Yellow Light: Filter Use = 80% - 99%
Red Light: Filter Use = 100%
