1234 12. Environmental-, soil-, water-, food analysis Sample analysis/COD GENERAL CATALOGUE EDITION 20 E & OE. TRS 300 programmable temperature and time control unit Programmable control unit for behrotest ® digester blocks. behr one-button operation for particularly easy and quick programming. Menu navigation in the language of the country. 10 optionally configurable programs for block temperature and digestion time. The TRS 300 has a special COD program which has already been set by the plant. Therefore in the operation mode "COD" it heats up to a temperature which is 20 °C above the set target temperature. After inserting the samples, the 20 °C higher target value remains for another 6 minutes. This procedure ensures heating up to 148°C within 10 minutes which is specified by the ISO norm, and at the same time causes extremely high temperature constancy during the subsequent reaction process. The supplied Windows software permits the user to transfer time/temperatures profiles, which are specifically for the application, via the RS232 interface in both directions between one or more units (TRS 300) and a PC. Temperature data can also be transmitted from the unit to the PC via the RS232 interface while operating. The user can save them if necessary and print them out as graphics. Integrated safety function switches the connected units off if there is a short-circuit and an interruption of the temperature sensor. 1 behr Type Description PK Cat. No. TRS 300 Temperature and control unit 1 6.229 909 1 behrotest ® HTI 1 manual titration station The HTI 1 manual titration station consists of - a burette with digital display and - a magnetic stirrer with a precisely fitting holder for COD reaction vessels. A screen serves as a neutral background and allows the user to determine the colour change at the end of the titration precisely. Therefore a titration could always carried out under similar visual conditions. This improves the precision and the reproducibility of the results. The precise positioning of the reaction vessels in the holder on the top of the magnetic stirrer also contributes to this. The angled wing of the screen protects against lateral dazzling light. 2 behr Specifications Voltage 230 VAC/ 115 VAC Frequency 50/60 Hz Weight approx. 3.5 kg Dimensions in mm (W x D x H) approx. 330 x 200 x 600 Type Description PK Cat.
