| A very versatile minimum/maximum temperature module with the LCD display and circuitry on one small PCB mounted on a battery holder, with a 17way edge connection. The module uses an external probe to display temperatures in the range -10°C to +110°C with a resolution of one tenth of a degree, in centigrade or fahrenheit. The module records both the highest and lowest temperatures measured by the probe, which are stored and updated in memory, and the maximum/minimum. values in memory can be displayed showing the highest/lowest temperature reached since the memory was last cleared. The maximum/minimum threshold values are fully programmable. Also included is a 12 hour digital clock, a 4kHz maximum/minimum. alarm output, separate outputs for relay drivers or similar which go high for 1 minute if the relevant programmed temperature threshold is reached, and a further output which pulses at 4kHz for 1 minute if either threshold is reached and then remains high until reset. There is a separate connection for a complete system reset. The external probe is included. |

| A comprehensive manual is supplied with the module showing how to connect a buzzer circuit to the alarm output and relay drivers to the high/low threshold outputs, and connections for the various functions and programming modes. The plastic bezel (FE35Q) can be fitted and increases the overall depth of the module to 27mm. Note that the meter itself and mainly the LCD display will only operate in the range of -5°C to +50°C. |
| The module requires a 1· 5V AA cell (not supplied). |
