Three Phase Site Energy Meter Test Instrument Type KP-P3001-A
-
Bofa Instrument & Equipment Co., Ltd
Three-phase site energy meter test instrument type KP-P3001-A (without voltage and current source) is an ideal instrument to test all kind three-phase energy meters accuracy below 0.2, especially for meters on site. When we want test a meter errors, the tested meter must be on load condition (or we can say the tested meter must be working). The instrument can test the errors, by comparing energy impulse from the tested meter with energy impulse from the reference meter which inside the instrument. The equipment is box structure and weight is very light, easy to carry, it is very convenience to test the installed meters on site.

Phase Monitors
-
NAI''s AC- and DC-powered Phase Monitors are used to protect three-phase loads from damage due to phase reversals or phase absence. Contacts may be used to disconnect the load or to operate alarm circuits or both. Upon application of power, the output relay energizes if all phases are connected and the phase sequence is ABC. If any phase becomes disconnected or if the phase rotation is abnormal, the relay immediately de-energizes. These monitors are specifically designed for rugged defense and industrial applications.

General Purpose Benchtop XRD System for Phase I.D. and Phase Quantification
-
In a move to bring lab-quality performance to the manufacturing floor, Rigaku introduces the MiniFlex XpC, a manufacturing-optimized powder diffractometer for fast and accurate quality control measurements. It is extremely easy to operate using Rigaku’s new EasyX quality control software, which requires minimal clicks to run. A minimal interface means there will be no accidental error variance from operator to operator. The MiniFlex XpC can be configured with a conveyor belt or robot for automated sample processing and collaboration with other instruments. With an 800 W X-ray source and a short-diameter goniometer, the system has the performance of a lab unit, and thus can greatly improve throughput for quality control measurements.
