Economical OIML Class M1 Hexagon-shaped Cast Iron Test Weights China Manufacturer 100g 200g 500g 1kg 2kg Hexagon Weights
Cast iron weights are a measuring tool that measures the weight of an object by comparing its mass. It is done by placing a weight on the balance pan while weighing the weight of another object. Cast iron weights usually have precise weight values because they are calibrated on a precision balance. When the balance weighs an object, the weight exerts a certain force on the balance, which in turn affects the balance point of the lever, thereby achieving accurate measurement of the mass of the object. ‌Field standards for testing industrial devicesClass III, Class IIIL or Class IIIITesting for non-marked scales withoutClass designationVerifying scales are within specified accuracy and tolerance
6 Million mPa.s Newtonian Non-Newtonian Liquid Brookfield Viscosity Measuring Meter Rotary Fluid Digital Viscometer
Working principle of digital viscometerDigital viscometers usually use the rotation method to measure viscosity. The instrument controls the rotation of the rotor through a stepper motor. When the rotor rotates in the liquid, it will be subject to the resistance of the liquid. By measuring the rotation speed and resistance of the rotor, the instrument can calculate the viscosity of the liquid and display it on the LCD screen.

0-50g and 0-100g Halogen Heating Moisture Analyzer
The moisture content is calculated by heating the sample to make it lose moisture, and then measuring the weight change of the sample. Specifically, the halogen moisture detector uses a ring-shaped halogen infrared heating source to quickly dry the sample, and measures the weight change of the sample in real time through a weighing sensor to finally determine the moisture content percentage. By injecting inert gas halogen elements, the life of the infrared radiation source is extended and the temperature is made more uniform. Compared with the traditional oven heating method, the halogen heating method is more efficient and the sample surface is not easily damaged.
With No. 0 Spindles NDJ-1 NDJ-4 1-100,000 Mpa.s 1-2,000,000 Cps Digital Dial Testing Rotary Viscometer Viscosity Meter
Rotational viscometer is an instrument used to measure fluid viscosity. It mainly measures the viscosity of various liquids by driving a stepper motor to rotate with high subdivision. Its working principle is to calculate the viscosity by measuring the resistance of the fluid during rotation. It is suitable for production and scientific research fields such as grease, paint, slurry, textile, food, medicine, adhesive, cosmetics, etc.

CE 0.1-2,000,000 Cps mPa.s Touch Screen Viscosity Test Meter Rotational Laboratory Viscometer Kinematic Viscosimeter
Kinematic viscosity (also known as the ratio of dynamic viscosity to density) indicates the ease with which a fluid flows.Kinematic viscosity is defined as the ratio of dynamic viscosity to fluid density at the same temperature, with the unit being (m^2)/s.Kinematic viscometers have a wide range of applications in industry and scientific research.By measuring the kinematic viscosity of a fluid, it can support quality control of the production process, product development, instrument calibration, and cost control.
