Features

The UVMINILOG is designed for high performance and reliable logging of ultraviolet radiation.

It uses sophisticated microcontroller technology and low noise SiC based UV detectors allow up to 18 months of permanent measurement and logging without battery charging.

Applications include dose monitoring of UV sensible goods such as artworks or compound materials. Other fields are dose monitoring of UV hardening systems or sun UV (e.g. Erythema or UVA + UVB) monitoring of persons, animals or plants.

Sensors

UV Sensors included
(available with one or two UV sensors)

The UVMINILOG includes sensors from the sglux TOCON series. The TOCON devices use modern hybrid technology to cancel unwanted signal disturbances caused by moisture or electromagnetic radiation. All TOCONs use a silicon carbide (SiC) detector chip.

By default we ship the device with a UVA-UVB-UVC broadband photodetector which is NIST traceably calibrated with a Xenon high pressure lamp (Newport 6251). Other NIST calibrated sensors such as sun Erythema, UVC disinfection, UV hardening and low UV sensing sensors are available on request. Please contact us for further assistance.

Optional Sensors

The UVMINILOG can be equipped with four further sensors:

	Measure:	Working range:	Accuracy
	Temperature	-10°C to +58°C	±0.1°C (5°C to 45°C) ±0.2°C (-10°C to +58°C)
	Relative Humidity	0-100% rel. Hum.( -20°C to +65°C)	±2% rel. hum. (10-85% rel. hum., 0 to 40°C) ±4% rel. hum. (85-95% rel. hum., 0 °C to 40°C)
	Pressure	0-2500 mbar abs.	±2.5 mbar (750-1100 mbar absolute)
	Acceleration	±10 G / ±2 G sel.	±0.15 g (25 °C)

Device

Data Transfer and Software

With the provided software Setup the user customises the properties of the UVMINILOG. With the software Reader the USB data transfer is started. The Viewer is used for graphical displaying. The data can be exported as a csv file for analysing in standard softwares like Excel or Origin. The software Online is displaying online measurements.

Logging Features

Record limits can be set for all used sensors. If a signal exceeds a limit the red LED will flash.

Measurements can be started via a connected computer (date and time for the start can be chosen) or manually by a push-button.

The push-button can be used as a marker to mark special events in the recording.

For each of the possible six sensors a measurement rate between 1s and 12h can be chosen.

Prediction feature calculates memory and battery capacity for the chosen measurement rates.

For monitoring of sensitive transport goods a shock measurement can be activated (if acceleration sensor is equipped). Therefore a threshold can be chosen. Every acceleration above this threshold is recorded. The mixing gravitational acceleration is not taken into account.

Attachment

The UVMINILOG has been developed for monitoring of moving goods and beings. It can be attached with a belt or three screws.

Versions

The UVMINILOG is available in different configurations. Besides the choice of sensitivity and spectral response of the UV sensors and the choices of additional sensors the device can be delivered in a waterproof (IP 67) housing. Please contact us for customised specifications and housings.
