DATA LOGGERS Tinytag Radio Logger Temperature /Relative Humidity Radio Frequency Radio Power Radio Range Radio Licence Memory type Logging Interval Offline Capacity Physical Specification 100m, Typical (Line of sight). One Week, at a Typical 8 Minute Logging Interval (see notes) 2 Programmable Latching Alarms (Upper and Lower) per Channel Software Warning Reading Specification Reading Range Sensor Type (External probe) Reading Resolution and Accuracy The accuracy quoted above includes the unit's thermistor probe. Relative Humidity Reading Range Reading Resolution Sensor Location Response Time *The thermal response of humidity measurement is 2.5 minutes. Operational Range* Case Dimensions *The Operational Range indicates the physical limits to which Battery Type Tekcell SB-AA11 or SAFT LS14500 Battery Life 6 Months, typical* *Battery life is dependant on the logging interval set and the number of loggers in a network. The above figure is quoted for a typical 8 minute logging interval and a network containing 50 A low battery warning will be displayed in the Tinytag Explorer software when the unit's battery needs replacing. Data stored on the logger will be retained after a battery is Batteries should be replaced in pairs. If used at low temperatures the data logger should be allowed to warm to room temperature before it is opened to avoid condensation forming inside the unit. The Offline Capacity of the logger is an indication of how much data the unit can store when it cannot communicate with a The IP67 rating does not apply to the unit's RH sensor. If moisture forms on the unit's RH sensor readings will become unpredictable. Once the sensor has dried out, and provided no residue is left behind, the unit should return to normal reading Any dust or residue that is allowed to build up on the RH sensor will affect the unit's reading accuracy. The sensor may be cleaned with de-ionised water or The RH sensor will resist small amounts of the following chemicals and substances: formaldehyde, carbon monoxide, sulphur dioxide, ethylene oxide, hydrogen chloride, hydrogen fluoride, hydrogen peroxide, nitrogen dioxide, methyl chloride, chlorine, freon, methanol, ethanol, isopropanol, ozone, diesel, automotive preservative, gasoline, motor oil, denatured alcohol, automotive solvent, window detergent, anti-freeze, bio-diesel, de-preservative agent, cleaner solvent, and battery acid. It also offers resistance to ultraviolet rays. Salt solutions may cause permanent damage as crystals forming within the porous layers affect moisture levels there.

DATA LOGGERS Tinytag Radio Logger Temperature /Relative Humidity This unit is configured to meet Gemini's quoted specification We recommend that the calibration of this unit should be checked annually against a calibrated reference meter. A UKAS traceable certificate of calibration can be supplied for an additional charge either at the point of purchase, or if the unit is returned for a service calibration. Gemini Data Loggers (UK) Ltd. operates a Quality Management System which conforms to ISO 9001. The scope of the system covers the manufacture, design and supply of data loggers and their...
