Multimeters
The TM351 was a high-accuracy digital multimeter designed for use on the workbench or on the go. It could check how much power a circuit used, how electricity moved through it, and how components limited or directed that flow across 26 selectable ranges—allowing users to test both very small and large values. Its accuracy of 0.1% meant it could measure with high confidence, even in precise applications. Its low-power LCD screen extended battery life, while the compact size made it ideal for technicians, students, and hobbyists needing a reliable all-round tester.
A more economical alternative to the TM351, the TM353 multimeter offered similar testing features across 26 manual ranges, suitable for checking power levels, signal flow, and component response in small circuits. While less precise—with a basic accuracy of 0.25%—it still provided dependable results for everyday electronics tasks. Its lightweight case and long battery life made it a practical tool for students, home users, and technicians alike, delivering professional capability at a more affordable price.
Designed with mobility in mind, the TM354 was small and light yet retained all the basic measurement functions required for everyday electronic work. It could measure AC/DC voltage, current, and resistance, and included a diode check—covering 14 test ranges in total. Its slim plastic casing recalls Sinclair’s earlier calculators, and the clear LCD made it practical for everyday use. Though less precise and versatile than Thandar’s larger instruments, it was among the most affordable in the range—offering reliable measurement tools to students, hobbyists, and technicians alike.
The TM355 used a bright LED display, making it ideal for dimly lit workspaces—though it required more power than the LCD-based models in the same range. It offered 29 test ranges and could detect very small currents, as well as high voltages up to 1000 V—from everyday electronic components and circuits to industrial systems. Like other Thandar multimeters, it could measure resistance and check diodes—components that allow electrical current to flow in only one direction. Usable with batteries or a mains adapter, it was suited to both portable and fixed setups.
This digital multimeter was used to test electronic components by measuring voltage, current, and resistance. It replaced the earlier TM353 model and offered 26 selectable ranges—suitable for detecting both very weak signals and higher-powered circuits. Like others in the Thandar range, it combined portability with bench-top use. This example is marked with the name of “Brunel Technical College”, most likely linking it to an educational setting in the UK. Instruments like this helped train future engineers as well as support routine electronic servicing.
