In response to the growing recognition of the benefits of 15 kV dc insulation testing, Megger, a world leader in portable electrical test equipment, has introduced two new instruments with 15 kV testing capabilities – the MIT1525 and the S1-1568.

• Resistance range up to 35 TΩ (S1-1568) or 30 TΩ (MIT1525)
• 8 mA noise rejection plus 4 filters (S1-1568)
• Safety up to CATIV 1000V to 4000 m
• Rapid charge Li-ion battery – meets IEC62133
• Operate with flat battery from an AC source
• Tough dual case design

Designed specifically to aid the installation of solar PV panels, Megger's new PVM210 solar irradiance meter features a compact design which, unlike most other irradiance meters, has the solar detector on the top of the instrument. This arrangement, combined with the useful measurement hold function, makes the PVM210 easy and convenient to use - even with just one hand - when working on a sloping roof or at the top of a ladder.

• Small, light and easy to use
• Designed for one handed use
• Safer for use on ladders
• Available as stand alone product, or in PV specialist kits

Easy to read display

The pocket-sized PVM210 offers fast accurate readings of solar power and shows the result on a large easy-to-read 3¾-digit liquid crystal display. This makes the instrument ideally suited as an aid to selecting the optimum position for PV panels during installation. In addition, it can also be used in conjunction with an ammeter to verify that the short-circuit current of a PV installation matches the specification provided by the manufacturer of the PV panels. For applications where precise irradiance measurements at a specific angle or in a specific direction are required, the instrument is provided with a tripod bush that allows it to be securely mounted on any standard photographic tripod.
