What to compare: standards and key specs

When choosing an instrument, compare measurable specs, not just brand names. Focus on measurement range, accuracy, resolution, sampling rate, and environmental operating conditions. For field work also verify battery life, IP rating on the product page, and accessory availability.

Brands and categories we stock

Communica carries thousands of products across test-and-measurement manufacturers and maker-favourite brands. Browse our Collections to refine by category or instrument type and see available accessories, probe options and spare batteries.

Selection guidance, accessories and compatibility

Match the instrument to your protocol: choose a data logger with sample interval and memory that fit your study, or a handheld meter with A/C weighting for occupational noise surveys. Don’t forget probes and adapters - many lab instruments need external RTD/thermocouple probes or external particulate sampling inlets to meet your use case. Check product pages for compatible probes before purchasing.

Practical spec callouts and quick calculations

Assessing measurement uncertainty: if a temperature sensor lists ±0.2°C and your process requires ±0.5°C, the instrument is suitable. For combined uncertainties, use the root-sum-square (RSS) method:

Combined uncertainty = sqrt(u1^2 + u2^2 + ...)

Example: sensor ±0.2°C and calibration ±0.3°C gives sqrt(0.2^2 + 0.3^2) = 0.36°C total uncertainty.

Field wiring and simple diagram

Many environmental sensors use 2- or 3-wire RTDs, 4-20 mA outputs, or simple serial/UART for logging modules. Typical 4-20 mA loop wiring (remote power and readout):

+24VDC ----[Loop Supply]----+----(Sensor)----(Transmitter)----+----(Meter/Input)

Confirm meter input type and whether you need an isolator. Our Collections page helps you pair meters with loop-powered transmitters and power supplies.

Availability, lead times and procurement support

Stock levels vary by item; many commonly used meters and data loggers are held at the Samrand warehouse for next-day branch pickup. For larger orders or campus deployments use Request a Quote so our team can confirm lead times, reserve stock and provide VAT invoices suitable for tender processes. Branch opening hours and collection details are on our Branches & Trading Hours page.

We understand educational projects and small lab budgets: Communica supports bulk procurement with consolidated invoicing and can recommend low-cost starter bundles for teaching labs - ask for accessory bundles that include probes, spare batteries and calibration plugs.
