Resistance Test Instrument Supplier
ZY9733 and ZY9734 digital desk type low current resistance measuring meters are suitable for units concerned to measure the DC resistance of various components and parts with certain limitations on current, such as platinum resistor, coppery thermal resistor, PTC ceramics, thermistor and various wire rods, etc.
1. Key features
1.1 It adopts a large green LED to display measured value, which is striking and clear. It also adopts the four-terminal resistance measurement method to eliminate the impact of conductor resistance, and the measurement accuracy is high.
1.2 There are a variety of specifications, and each specification has four scales to meet the measurement requirements of different users.
1.3 The test current is lower than similar equipment, which effectively prevents the impact of components and parts on resistance.
1.4 ZY9734 type has a RS-232 serial data output interface to facilitate the connection to computer.
1.5 It adopts a novel plastic shell and can changes the inclined angle between the device and table by adjusting the handle position, so as to determine the suitable panel observation angle. It has a well-designed appearance and is easy to use.

The digital compression testing machine with dedicated universal computer software for reading purpose, self operating & monitoring has been designed to meet the need for a simple, economic and reliable means to test concrete / cubes etc. For its compressive strength. The design expressive of simplicity, both of construction and operation, makes the machine easy to use and maintain. The unit is compact, making it useful for site and
Laboratory applications.
Features:
•High stability four pillar load frame.
•Each frame tested for stability and alignment to avoid tension failure during a test and to ensure centre loading.
•A precise large diameter spherical upper platen for optimum results.
•Motorized hydraulic power pack or pumping unit with rapid approach and automatic over load protection.
•Comes standard with safety guards on all four sides
The complete unit comprises a loading unit which is of four pillar model construction having a cross-head with a spherical seated platen. The lower platen is attached to the top of the piston. The loading capacity is of 2000 kn, cubes up to 200 mm & cylinders up to 150 mm dia x 300 mm height can be tested using the appropriate spacers.
Pumping unit attached to the loading unit by high pressure hydraulic flexible hose pipe. The pump facilitates rapid approach of the platens for daylight closure and also provides comprehensive control over the application of load.
A control valve provides fine control over the loading rate for accurate pacing.
Maximum load is held and retained for approx. 15 min, unless cancelled, using the panel mounted reset switch. Pace rate set for running the test can be maintained manually.
