$ HOBO U23 Pro v2 Temperature/Relative Humidity Data Logger - U23-001A. Sensor Output Type (e.g.
**Only Relative Humidity and Temperature are recorded on internal logging, not Flood. Data loggers provide automated data recording and are an ideal solution for standalone monitoring requirements, such as temperature loggers within one or two fridges.

for information on the appropriate Current Clamp to be used. Data Logger monitors Temperature and Humidity and is suitable for outdoor use.Temperature Measurement Ranges between -40°C to +60°C. Radiant Flux in that includes all electro-magnetic waves emitted, while Luminous Flux is weighted according to a model/Luminosity Function of the human eye's sensitivity to various wavelengths of electro-magnetic radiation.Therefore, to be clear, the Lumen is a measure of the total quantity of visible light emitted by a source weighted so it is as would be seen by the standard human eye.Damage from light is cumulative in its effect; that is, the longer you leave an item exposed to light, the more damage the exposure will cause.Reducing the damage done by light means considering both intensity of the light (Lux) and the length of exposure.A delicate watercolour exposed to 50 Lux for 100 hours will experience the same damage as if it were exposed to 100 Lux for 50 hours.Prior to EMS Version 1.0.10 ( 2.0.3 EMS Compliant) Cumulative Lux is expressed as the sum of all Lux readings.From EMS Version 1.0.10 (2.0.3 EMS Compliant) onwards, Cumulative Lux is expressed as Lux/Hours over the elected period.

Unit is a Thermocouple Wireless Data Logger which includes an LCD display and operates on the 434.075MHz frequency as standard. One Lux is defined as a brightness corresponding to one is spread over a given area; that is, a measure of the intensity of illumination on a surface) is a measure of the total ‘amount’ of visible light present. Radio Transmitter is fitted with onboard Temperature and Humidity Sensors.Humidity Measurement Range: 0 - 100%RH non-condensing. Download the Basics Guide! Radio Transmitter is fitted with onboard RH/T sensors and is compatible with an optional additional flood probe. to get the required Gain and Offset; in this case the values will be 3.052503 and 819.Enter the values calculated by the above table into the These values are then sent to the Device when it is Synchronised with the EMS Database.For further information on Gain and Offset calculation, please refer to Document:Connecting 4000 Series Linear Sensor-Transmitter/Data Logger Units to External ProbesSensor-Transmitter Units supplied with wiring for external probes (see example in 187  above) should be connected to them as follows:Any unused pairs of wires should be twisted together. Data Logger is fitted with Remote LUX and UV probes. is a slimline Single Channel Thermistor Unit with an External Temperature Probe*Door Status is only recorded on internal logging at the pre-set logging interval. These probes can be calibrated by the users or at Hanwellâ€The data logger is set-up and downloaded using an integrated software package, which automatically recognises the type of unit connected to the PC via the USB lead. Transmitter provides Temperature measurement and is fitted with a door switch, LCD display and 2 Pin Lemo socket.Temperature Measurement Range: -20°C to +60°C which is extended to -40°C to +100°C with external probesThe RL407 is a slimline Single Channel Thermistor Unit with fitted with an internal temperature sensor. is a measure of the brightness of the incident light but measured in such a way as to be comparable with the subjective opinion formed by the human eye.In practise this means choosing a detector that has a similar spectral response to our own eye.
