Low hardness of water Test Kit in competitive price

Measuring range: 0.4-20mg/L (calculated as CaCO3) Packing: 50 tests/box Fast, Easy-to-Use, Accurate

Low hardness of water Test Kit

1. Specification

Name: Low hardness of water Test Kit

Model: LH-P08

Type: quantitaitve

Color reaction: none-bule-purple

Measuring range: 0.4-20mg/L (calculated as CaCO3)

Packing: 50 tests/box

Method: titration

Application: The test is used after the water-softener stage of the clean-up process. Softening is a pretreatment for water that usually undergoes further purification processes like reversed osmosis. Hard water can damage the delicate osmosis units, thus decreasing its effectiveness and operating life.

Shelf life: at least 1 year

 

 

 

2. Feature

Convenient to use:

Light weight and small size, suitable for detection on site, and minimize the errors caused by long transportation; Standardized operation, and minimized manual errors; Real-time monitoring of ozone concentration in production process.

Accurate Measuring:

Scientific formulation, special techniques, and strict quality control; Research and development conducted under international standards and methods; Produced from imported materials, including color agent, buffer agent, spiking agent, and covering agent, etc; Standardized precise colorimetric cards specialized for colorimetric tubes; Double layers aluminum foil, preventing moisture and light.

3. Operation

1. Use the transferpetter measure 15mL testing liquid to Erlenmeyer flask.

2. Add a pack of reagent I, sway the flask, if the liquid become blue, the hardness of water is below 0.4mg/L, or please go to step 3.

3. Use another transferpetter measure 1mL reagent II.

4. Add reagent II while swaying the flask till liquid turn blue from purple, repeat step 3 and 4 when 1mL is not enough, record the volume V.

5. The hardness of the testing liquid =V*20 (mg/L, calculated as CaCO3).

Notes:

1. Wash the Erlenmeyer flask with deioniazed water before testing.

2. The PH of testing liquid must be controlled between 6 and 9.

3. Avoid bubbles when measuring liquid with transferpetter.

4. Fields of Application

Household drinking water and water sources, surface water, aquiculture water, irrigation water, seawater, household and industrial wastewater and etc

Various industries involving large amount of water require frequent water testing, and the controlling of water quality to meet the different standards. In the case of water deterioration, water tests must be conducted immediately, so measures can be taken accordingly, to prevent serious consequences.

The testing packs are very convenient for on site operation, and can satisfactorily meet the requirements in various industries.
