Gemini Data Loggers of Chichester has announced fist-sized data loggers that run for up to two years on a battery.

Called the Tinytag Instrumentation range, they measure:
voltage
0-2.5Vdc – 0.1mV resolution
0-25Vdc – 1mV resolution
current
0-25mAdc – 1μA resolution
impulses
0-14,000 – 50 counts per second max

When connected to a variety of third party sensors, the firm sees them recording pressure, flow rate, rainfall and footfall, amongst other applications.

Two sorts are available:

Plus 2 (yellow)
rugged
waterproof
no display
80 x 59 x 34mm
Change battery at 2years
Gemini-Data-Tinytag-spashproofView 2 (blue)
splashproof
with display (resolution 0.1V or 0.1mA)
60mm dia x 35mm deep
Change battery at 1year

In both cases, the battery is a 14250 (14mm dia x 25mm tall – ‘half AA’) lithium thionyl chloride primary cell

Custom specifications an be factory configured, allowing the device to show readings appropriate for the sensor they are connected to.

Each customised data logger is provided with a unique reference number, enabling customers to place repeat orders in the future without having to resubmit the scaling data.

If a user wishes to change the sensor that the logger is attached to, the firm provides a rescaling service.

“We are very pleased to launch this Tinytag Instrumentation range,” said Gemini Data Loggers sales manager Nigel Palmer. “The loggers can monitor almost any condition by interfacing to a vast range of sensors. With custom configurations available in just 10 working days, this new family enables customers to rapidly deploy efficient data logging solutions to measure the conditions that matter to them.”

Gemini has been manufacturing data loggers since its establishment in 1984. The firm trades globally through more than 40 distributors.
