- Additional equipment (specified when ordering)
Replaceable studied modules NTC-18.74 / 01 (made of steel pipe filled with mineral wool) and NTC-18.74 / 02 (made of steel pipe filled with gypsum) are intended for alternate use in laboratory experiments No.1 and No.2.
The replaceable research module NTC-18.74 / 03 is intended for laboratory experiment No. 3 and No. 4. It has the ability of horizontal and vertical mounting. Also, the replaceable module НТЦ-18.74 / 03 is used alternately with the module НТЦ-18.74 / 04 (made of a copper pipe filled with shot) during laboratory experiment No. 5.
The following equipment is located inside:
- digital temperature meter – 8 pcs.;
- multi-tap step LATR – 1 pc.;
- step-down transformer – 1 pc.
A power switch and LED indication of power-on, network fuses, a digital wattmeter, switching equipment for turning on and controlling the LATR, allowing changing the heating intensity of heating elements during laboratory experiments, are installed on the stand panel. Temperature meters have a USB interface for connecting to a computer. Digital instruments provide measurement of electrical active power with class 1 accuracy.
The training system is accompanied with:
- a set of teaching materials and technical documentation intended for the teaching staff;
- a software.
Experiments provided
