Quotation for CST sludge capillary water absorption time measuring instrument in universities

1. CST capillary water absorption time tester/Sludge capillary water absorption time measuring instrumentModel: HDFC-10A

Overview

The CST capillary suction time tester has been widely used since 1970 and can be applied in multiple fields. In urban sludge dewatering pretreatment, the CST is used to determine the difficulty level of sludge dewatering, determine the selection and dosage of PAM, and optimize the dosage of PAM; Due to the filtering ability and state of sludge affecting the output of almost all types of dewatering equipment, including drying beds, belt presses, vacuum filters, filter presses, and centrifugal separators, the operation of these equipment can be guided by the fast and reliable measurement of CST, which can play a cumulative role; In the testing and research of oilfield chemical treatment agents, CST values are used to evaluate the mud's ability to inhibit dispersion, the drilling fluid's ability to prevent expansion, the drilling fluid's ability to inhibit hydration dispersion, and optimize the formulation of the wellbore fluid, such as the type, dosage, and ratio of treatment agents. They can also be used as a new method for analyzing and evaluating shale classification. In the process of flocculation treatment of waste drilling fluid, CST values intuitively reflect the destabilization situation and determine the flocculation performance of coagulants, in order to use screening coagulants and their concentrations.

2.Ozone tester/water ozone tester/water ozone detector Model: HHXH-O3

The ozone tester is suitable for detecting ozone concentration in large, medium, and small water plants, mining enterprises, domestic or industrial water, in order to control the ozone in water to meet the specified water quality standards. This instrument applies the principle of microcomputer photoelectron colorimetric detection to replace the traditional visual colorimetric method. Eliminating human error, the measurement resolution is greatly improved. When measuring, when the tested water sample is poured into the reagent, the water sample will turn pink. Then place this water sample into a photoelectric colorimetric stand, and the instrument will determine the concentration of ozone based on the depth of pink.

3.Photoelectric photometric formaldehyde detector Model: FP-31

FP-31 formaldehyde detector detection principle:
The concentration of formaldehyde in indoor air is measured using the photoelectric photometry method. When formaldehyde gas passes through the detection unit, the paper soaked in a coloring agent in the detection unit changes color from white to yellow due to a chemical reaction. The change in reflected light intensity caused by the degree of discoloration is a function of formaldehyde concentration. Measure the concentration of formaldehyde based on the rate of change in reflected light intensity. Wait for the instrument to reach the test paper reaction time to read the value.

Formaldehyde measurement steps required by the standard

1. Read the value when the instrument reaches the reaction time of the test paper
2. Repeat every 10 minutes, repeat three times and take the arithmetic mean of the data
3. Record on-site temperature, atmospheric pressure, and relative humidity
4. The instrument vent is 1 meter away from the front breathing zone of the human body

Conversion of concentration units:
For the conversion relationship between the measured value of quality score and mass concentration:
Cp - formaldehyde mass concentration, mg/m3
C '- Quality score measurement value, μg/g
B - Molar volume of gas under standard conditions (0 ℃, 101.3kPa)
B=22.4L/moL
