The operation of the density meter is based on measuring the oscillation period of a hollow tube of the original configuration filled with the liquid under study, and then calculating the value of its density using the results of preliminary calibration for two substances of known density, for example, air and water. • Maximum viscosity of the measured liquid at ambient temperature 300 mm2/s The nominal volume of the measuring cell is 1.5 ml Measurement time of 2 channels 20 s • Temperature range of the built-in thermostat +15...+60 °C • • Overall dimensions 205x225x80 mm Weight 3 kg Power consumption 15 W

LTA-MF provides an error of ±0.2 °C in the measured temperature range from -196 to +200 °C The minimum immersion depth of the sensor is 75 mm Overall dimensions of the electronic unit 80x75x100 mm Weight 0.25 kg

METOLAB 451 is a stationary hardness tester for measuring various materials using the Vickers method (HV scale) in full compliance with GOST R ISO 6507-1-2007. Due to its characteristics, the device allows you to measure the hardness of steels, cast iron, non-ferrous metals, soft alloys and other similar materials. The hardness tester is equipped with an electronic load value switch, has the functionality of entering diagonal length values from the control panel with subsequent automatic calculation of hardness. It is also possible to note a wide range of measured values (from 5 to 2500 HV) and the range of the applied load (from 1 to 50 kg). The automatic METOLAB 451 Vickers hardness tester is included in the State Register of Measuring Instruments of the Russian Federation (GRSI) and comes with a certificate of primary verification (on request). The entry number in the GRSI is 67656-17. Distinctive features of the stationary METOLAB 451 Vickers hardness tester: Simple and intuitive control of the device; Simplicity and ease of maintenance of the hardness tester; Wide range of measured values – from 5 to 2500 HV; Automatic application of test loads in the range: 1 kg (9.8 N); 2 kg (19.61 N); 3 kg (29.4 N), 5 kg (49 N), 10 kg (98 N); 20 kg (196.1 N); 30 kg (294 N), 50 kg (490 N); The price of dividing the scale of the reference microscope: 0.5 microns at 200x, 1 microns at 100x; The hardness tester is equipped with an electronic load value switch; A bright and clear LCD display that displays all the necessary service information, including the selected scale, the set load, exposure time, test mode, etc.; An automatic loading system guarantees high accuracy and repeatability of the results.
