Laboratory EM current meter / water level and wave height meter
-
ACM2-RS and ACM3-RS are 2-D and 3-D electro-magnetic current meters for laboratory experiments. The models provide digital output, a high-speed sampling rate and insusceptibility to electro-magnetic noise. ACH-600RS is a highly sensitive capacitance water level meters. With the new system, a maximum of four different sensors can be connected to the compact interface unit, enabling simultaneous recording on a personal computer. Additionally, the system can provide analog output as well as necessary. While conventional water level and wave height meters cannot be used near velocity sensors, our instrument can be as near as 5 cm without increasing noise, due to its special isolated circuit. The result is an innovative system that is capable of achieving highly accurate data.

Low Current Probe 80A
695
-
Great tool for accurate measurement of low current. Use with your graphing meter or lab scope to view current waveforms on fuel injectors, fuel pumps, primary ignition coils and more. Also works very well with digital multimeters. Resolution of 10 milliamps is low enough for most parasitic drain testing. In addition, the clamp opening of 1/2 inch is large enough to clamp over most negative battery cables for those parasitic drain tests.
