 |
Overview | |
| MicroCal have been developed using the most advanced microprocessor technology to provide high accuracy on extended ranges and a powerful operating flexibility. The case, made in shock-resistant ABS, is ergonomically designed for easy practical use. The instruments are powered by four Ni-MH rechargeable batteries; an external battery charger is supplied as a standard accessory. |
