CENSA precision balance series 600–5000 g / 0.01 g

COLO.SCIENCE — CENSA SERIES

CENSA precision balance series, 0.01 g readability, five capacities from 600 g to 5000 g

The CENSA precision balance series covers routine laboratory weighing from 600 g to 5000 g at one uniform readability of 0.01 g. A high-precision load cell, OIML Class II accuracy, backlit LCD, external calibration and an RS232 output give the same operation and the same data workflow on every model: CENSA600, CENSA1000, CENSA2000, CENSA3000 and CENSA5000.

SELECTION NOTE — CENSA PRECISION BALANCE SERIES

CENSA600 covers 600 g for small samples, teaching laboratories and limited bench space. CENSA1000 and CENSA2000 are the usual choices for general bench weighing. CENSA3000 and CENSA5000 extend the same 0.01 g resolution to heavier vessels and larger sample batches. Because the resolution does not change with capacity, there is no reason to pick a smaller model than the heaviest load actually requires.

Key characteristics of the CENSA precision balance series

One 0.01 g platform across the full capacity range

The CENSA precision balance series is built on one measuring platform shared by all five models, so a laboratory can standardise operator training, calibration procedure, accessories and data handling while still choosing the capacity each bench actually needs. A laboratory that runs a 600 g balance for reagent weighing and a 5000 g balance for bulk sample preparation works with the same keypad, the same tare behaviour, the same calibration routine and the same RS232 output on both instruments.

That consistency matters in practice. When two balances on the same bench behave differently, every procedure has to be written twice and every new operator has to be trained twice. Because the CENSA precision balance series keeps readability at 0.01 g and the accuracy class at OIML Class II regardless of capacity, a written weighing procedure can be applied across the series without revalidation for each capacity. The series uses external calibration throughout, so one documented calibration routine and one control weight class — OIML M1 — cover the whole family.

Models, SKU and capacities of the CENSA precision balance series

Repeatability ±10 mg and linearity ±20 mg apply to every model of the series. The SKU shown on each card is the COLO product number used on quotations and order confirmations.

Operating and weighing functions of the CENSA precision balance series

Construction, protection and power supply

• Load cell and pan. A high-precision load cell carries a stainless steel weighing pan that can be wiped down and does not corrode from spilled reagents.
• IP43 protection. The housing is rated IP43, which covers the dust and splash exposure of ordinary laboratory and workshop benches.
• Levelling. Adjustable feet let the balance be levelled on a bench that is not perfectly flat — a condition for reaching the stated repeatability.
• Power supply. Mains operation is AC 110–240 V, 50/60 Hz through a DC 5 V / 2 A adapter, so the same instrument works on any of the usual supply voltages.
• Optional built-in rechargeable battery. An internal accumulator can be fitted at the factory for benches without a nearby socket, for mobile sampling or for sites with unreliable mains.
• Operating conditions. 15–30 °C with a temperature drift below 5 °C/h and 40–80 % relative humidity; avoid draughts, vibration and direct sunlight on the pan.

Applications and operational value of the CENSA precision balance series

How to select the right CENSA model

Selection starts from the heaviest load that will ever sit on the pan — the sample together with its container. Add a reasonable margin and choose the model whose maximum capacity covers that total: 600 g, 1000 g, 2000 g, 3000 g or 5000 g. Since readability stays at 0.01 g on all five models, a larger capacity costs nothing in resolution, and a balance that is too small simply cannot be used with a heavy beaker or flask.

Three further questions settle the configuration. Do results have to leave the balance? If yes, add the RS232 cable with a thermal printer for paper records, or the communication software for transfer to a PC. Will the balance be used away from a socket? If yes, specify the built-in rechargeable battery at the time of order, since it is fitted at the factory. Does the laboratory procedure require documented calibration? If yes, order the OIML M1 control weight matched to the capacity, and the calibration certificate for the weight, the instrument, or both.
