HWg-Tg11: GSM temperature datalogger - not produced any more

GSM thermometer with temperature logging and alerting over SMS and e-mail (GPRS). In addition, Tg11 works as a temperature logger - it stores temperature values in its internal Flash memory (every 15 minutes) and e-mails stored data (every 4 hours) over GPRS.

Note: This product is out of production. Was replaced by GSM Thermometer HWg-Ares12

 

HWg-Tg11 GSM temperature datalogger is an effective solution for reporting temperature alerts and temperature logging in remote places or in vehicles.

Temperature sensor in stainless-steel housing is connected with a 3m silicon cable and measures temperatures from ‑30°C to +125°C.

  • When the temperature leaves a defined safe range, Tg11 rings a preset number and sends a warning SMS.
  • Temperature readings are logged every 15 minutes. The entire log is e-mailed over GPRS every 4 hours.
  • Tg11 cooperates with the SensDesk web portal. Past values and alert responses are archived on a central server. Connection to the SensDesk portal is available as a subscription-based service.
  • The status of Tg11 can be verified by ringing its number or sending a SMS. The device replies with a status SMS.
