Universal Circular Chart

The CTXL Superecorder circular chart recorder comes in three models: CTXL-TRH, CTXL-DTC, and CTXL-DPR.

The CTXL-TRH is a temperature/relative humidity recorder with a range of 17 to 49°C and 2 to 98%, respectively. The CTXL-DTC dual thermocouple input chart recorder accepts J, K, or T-Type thermocouple probes. The CTXL-DPT dual-process input recorder accepts 0 to 1-Vdc, 0 to 5-Vdc, 0 to 10-Vdc, 0 to 20-mA, and 4 to 20-mA inputs. The microprocessor-based, portable units have dual backlit LCDs. Data is stored in nonvolatile memory and can be downloaded to a PC. Additional functions include audible and visible alarms with built-in relay contacts; real-time clock monitors; monitoring of minimum, maximum, and average times; one, seven, and 32-day recording; chart rescaling; and front-panel keypad programming.
