【7 in 1 Function】This is a water test kit with PH meter, TDS meter, TEMP meter, EC meter, Salinity meter, SGmeter and ORP meter test function. The backlit LCD display makes it easy to read the displayed values.
【Automatic temperature compensation】Temperature may affect the reading level, automatic temperature compensation ensures that the test temperature is within the range of 0°C to 60°C for better readings.
【Multifunctional】This is a water test kit with PH meter, TDS meter, TEMP meter, EC meter, Salinity meter, SGmeter and ORP meter test function. The backlit LCD display makes it easy to read the displayed values.
【Measurement range】PH value: 0-14pH; TDS value: 0-200000ppm; EC value: 0-200000uS/cm; Salinity: 0-25%; ORP negative potential: ±1999MV; H2 hydrogen rich: 0-2400PPb; The specific gravity of S.G seawater is 1.000-1.222; Temperature: 0-60℃.
DETECTION OF RADIATION: Geiger counter technology tube, counting instrument for detection of nuclear radiation(β ray, Y ray and X ray) strength, possess high sensitivity
ALL ALUMINUM ALLOY SHELL: The nuclear radiation detector adopts imported aluminum alloy shell, which breaks the traditional material and possesses good strength and good corrosion resistance
【Surface Roughness Comparison Sample Block】The surface roughness comparator is designed for comparing and testing the smoothness of mechanical workpieces. It allows for visual inspection or microscope examination to determine the degree of surface roughness.
【30-Piece Composite Bag Fixing Gauges】The package includes 30 fixing gauges, each representing a different surface roughness. Among them, 3 flat grinding gauges measure 2, 4, and These gauges provide true and consistent reproductions of surface finish, allowing users to accurately assess the feel, appearance, and texture of machined parts.
【Multiple Roughness Grades】The standard set typically includes a range of samples with 30 levels of roughness.
【Stability & Durability】These standard sets are made of 45# carbon structural steel which is stable and durable materials to ensure accuracy and reliability during long-term and repeated use.
The notebook sample block contains standards for the six most important processing methods among the popular "AA" values. All 30 samples were calibrated with uAA (arithmetic mean) and metric equivalent um Ra.
