SM-850 Salinity Meter

SM-850 conductivity type salinity meter can measure the salt content in broth or mixed liquid.
Ordinary optical salinometers cannot accurately measure the salt content in the mixed liquid, or when the soup contains fat, it cannot be measured by optical methods.
But through the conductivity method, the salt content in the broth or soup can be accurately measured.

Product ID: SM-850
Micro Processor Base Salinity Meter ( SM-850)
Model SM-850 Features:
_Portability and simplicity one-hand operation
_Dual display Salinity and Temperature
_Automatic Temperature Compensation
_Average calculation, interval measuring,
_Use highly accurate NTC temperature sensor
_Auto power off function

We follow well defined strict quality control measures and each and every electrode is checked individually for its performance and quality by our Q.C. Department.

pH-703 pH Meter

pH meter

pH meter is electronic instrument used to measure the ph of a liquid. There are many ways that can measure pH. But if you need higher pH precision, pH meter is the only way to go.

Typical pH meter consists of a special measuring probe connected to an electronic meter that measures and displays the pH reading.

Our pH meter can be used in various fields, such as pool, aquariums, hydroponics, school laboratories, cooling towers, food processing water testing, sanitation plants , printing, and chemical industries. As customers use our products, we provide accurate, reliable results of pH meter.

There is a tip that can help you use the pH meter correctly. Before use pH meter must be calibrated because each pH electrode is slightly different and its characteristic changes with aging.

Depending on the pH meter type it may either recognize buffer automatically and perform calibration procedure on its own or you will have to calibrate it using knobs and changing buffers when every time you use it. So before buying a pH meter, there are a lot of functions that you should consider.
