YD200 type water quality hardness tester
Technical parameters :
Definition and conversion of water hardness unit:
1.1. mmol/L — Basic unit of water hardness
1.2. mg/L(CaCO3)
1 mg/L(CaCO3) = 1.00×10-2 mmol/L
1.3. mg/L(CaO) —
1 mg/L(CaO) = 1.78×10-2 mmol/L
1.4. mmol/L(Boiler)
1 mmol/L(Boiler) = 5.00×10-1 mmol/L
1.5. mg/L(Ca) —
1 mg/L(Ca) = 2.49×10-2 mmol/L
1.6.ºfH(France)— Indicates water hardness that water contains 10 mg/L CaCO3or 0.1 mmol/L CaCO3
1ºfH = 1.00×10-1mmol/L
1.7. ºdH(Germany)— The water hardness of the water containing 10 CaO mg/L
1ºdH = 1.79×10-1 mmol/L
1.8. ºeH(British )— Said the water contains 1 grains per gallon in Britain,it means that water hardness in 14.3 mg/L or 0.143 mmol/L CaCO3
1ºeH = 1.43×10-1mmol/L
1.9. Water hardness unit conversion:
1mmol/L = 100 mg/L(CaCO3) = 56.1 mg/L(CaO) = 2 mmol/L(Boiler)= 40.1 mg/L(Ca) = 10 ºfH = 5.6 ºdH = 7.0 ºeH
2.0 technical parameters of equipment :
2.1. Measure range :
(a)water hardness value:1.50×10-2 ~1.00×102 mmol/L
Equivalent to other units: 1.50 ~ 1.00×104 mg/L(CaCO3)
8.41×10-1 ~ 5.61×103 mg/L(CaO)
3.00×10-2 ~ 2.00×102 mmol/L(Boiler)
6.02×10-1 ~ 4.01×103 mg/L(Ca)
1.50×10-1 ~ 1.00×103 ºfH( France )
8.40×10-2 ~ 5.6×102 ºdH(Germany )
1.05×10-1 ~ 7.00×102 ºeH (British )
Note :ºeH,ºdH,ºfHCan only choose to use in the WH-Link communication software
(b) temperature :0-60.0℃ .
Note :temperature is ℃and ℉,setting by user .
