Atmospheric analysis

This telemetry-capable data logger is designed for remote operation and used extensively in NIWA's national hydrometric network of water level monitoring stations.

This Weather Transmitter is a compact and lightweight multi-sensor instrument that measures the six most essential weather parameters and has no moving parts.

This miniature transmitter measures humidity from 0 to 100% and temperature from -40 to +60 degC. It uses little power, and you can remove its sensor to simplify calibration.

For WMO-standard accuracy and stability we use HMP155 probes to measure Relative Humidity and air temperature in our Electronic Weather Stations.

Black petrels are relatively few in number and are sometimes caught on fishing lines and in nets. The effect of fishing-related deaths on the population is unknown.
