level of accuracy	Level 0.05
Piston material	Tungsten carbide
Weight material	Tungsten steel or stainless steel (optional)
Basic error	The basic error is ±0.05% of the actual measured pressure over the entire measurement range.
use	Can be used to test piston pressure gauges, float pressure gauges, pressure sensors, pressure transmitters, digital pressure gauges and other precision pressure gauges

Technical features:

● Small size, light weight and easy to carry. Host 6kg, KY0.6 weight 6kg; KY6 weight 12kg, KY25 weight 25kg; KY60 weight 30kg.

● It can be carried to the site for operation (on the premise that the ambient temperature is satisfied), and the measurement accuracy is not affected at all.

● The piston and cylinder are made of tungsten carbide with high strength, high hardness and low temperature coefficient of expansion. After calculation, the deformation error is negligible; the working environment temperature can be relaxed to 20±5°C; the performance is very stable.

● The piston and the cylinder are precision ground, and the roundness error and the gap are extremely small, thus ensuring the sensitivity of the pressure gauge.

The certificate of China Institute of Metrology or Shanghai Metrology and Testing Institute is attached to the factory.
