Temperature recorder DR401

Temperature recorder

Model: DR 401 

Description:
- 2 temperature sensors
- 3 input signals
- temperature alarm
- hermetic housing
- supply 12 .. 24V or 230V

Recorder DR-401 is designed to measure and record temperature of one or two temperature sensors and events with up to three digital inputs. The measurement data are stored in non-volatile memory of the recorder. The frequency of data memory can be programmed in the range from 1 to 999 minutes. Memory capacity is 13 000 measurements (enough for almost a year at a frequency of 30 minutes). The stored data can be erased, and the entrance to the menu password protected. The recorder is equipped with a thermal printer so that you can print the data from the memory device for any period of time. Print report allows to trace the entire history of transport. The user has the ability to program the minimum and maximum temperatures for each sensor, beyond which alarm will be informed on the display, a sound signal and an active state of the relay. Operation is simple and intuitive, all messages are displayed in the Polish language. The recorder has a function of "supply", which allows you to identify the start and end of the course on the printed report (loading and unloading). The DR-400 kit includes 2 NTC temperature sensors for wall mounting. They allow the measurement of temperature in the range -40 ... + 80 ° C ± 0.5 ° C. The instrument can also work with sensors Pt1000 in the scope -200 ... + 650 ° C and used for archiving industrial processes. The instrument is designed to control the transport and powered vehicle electrical system 12 ... 24V. There is a stationary version of the mains 230V. Optionally available sensors are also opening doors, external sounders and a certificate of calibration of the instrument.
