The spectrometer was created according to the Cherni-Turner scheme based on a flat diffraction grating and an MAES analyzer with one line of photodetectors. It has increased photometric accuracy due to cooling and temperature stabilization of the photodetector range, as well as due to its shell-less design, in which there is no re-reflection of radiation on the cover glass and the background level in the recorded spectrum decreases. The optical scheme and design of the spectrometer are optimized to obtain a high-quality spectrum with a low level of background radiation in any of the regions lying in the spectral range of 190-1100 nm. The choice of the working area is carried out by changing and rotating the diffraction gratings. The sealed case of the spectrometer is filled with an inert gas. The radiation is injected into the spectrometer using a quartz capacitor or a fiber-optic cable with an SMA-905 connector. The optical scheme and design of the spectrometer are protected by patents.

The working condition of the ND-630 diffusion pump depends on the temperature of the working fluid in the pump boiler. During the initial filling, it is recommended to fill the maximum volume of the working fluid. Working fluid is "VACMA OIL 500" vacuum oil (uner technical specifications TU 19.20.29-061-00218526-2019). The total amount of working fluid in the ND-630 diffusion pump is a maximum of 9 liters, a minimum of 6 liters. The viewing window for visual inspection of the working fluid has marks of its maximum and minimum amounts. During normal operation of the pump, the level of the working fluid practically does not change. The temperature of the working fluid when the pump is operating at the maximum residual pressure is about 240°C to 255°C. It is recommended to monitor the operation of heaters in the ND-630 diffusion pump using one temperature sensor. The temperature sensor must be installed in a special radiator socket above the heater. If there is a loss of working fluid and an increase in the temperature of the radiators of the ND-630 diffusion pump up to 360°C, the temperature sensor must give the command to automatically turn off the heaters. The subsequent activation of the pump heaters should not be automatic and should be performed only after cooling the system. Water at the inlet to the cooling systems of the housing and the oil reflector must be supplied with a pressure of 0.3 MPa (3 kgf/cm2) to 0.5 MPa (5 kgf/cm2) and a temperature of plus 4°C to plus 25°C. The recommended cooling water consumption for the housing is 600 l/h, for the oil reflector it is 80 l / h. It is regulated by the outlet water temperature, which should not exceed plus 40°C. The water drain should be free (with a jet break).

It is intended for thermostating samples in glasses, flasks and other laboratory utensils in cases where high accuracy of temperature maintenance is not required and good uniformity of the temperature field in the working volume is not needed. The operating temperature range is Current +5...+200 °C. One workplace with a diameter of 110 mm with five steel O-rings. Stamped steel bath with a volume of 3.5 liters and a depth of 100 mm. Bath volume 3.5 l Overall dimensions 325x195x310 mm The open part of the bath is 235x130 mm Weight 6 kg Power consumption 2.5 kW
