The 27 II digital multimeter defines a new standard for operating in harsh conditions with the features and accuracy to troubleshoot most electrical problems. Both meters have IP 67 rating, MSHA approvals , extended operating temperature range of 5 degree F to 131 degree F, -40 degree C for up to 20 minutes and 95 % humidity, and have been designed and tested to withstand a 3 m (10 ft) drop. Measure up to 1000 V ac and dc. Measure up to 10 A. 10,000 capacitance range. Frequency to 200 kHz. Extended ac voltage bandwidth 40 Hz to 30 kHz.
The 27II has a 6,000-count display, able to show 59.99 on a given range. It comes with a dual brightness backlight display and updates at around four times a second, which is a decent speed for monitoring changing signals. Although not as high a resolution as the 28 version, you also get a speedy bar graph built into the bottom of the display. It updates 10 times faster again and is able to pick up fluctuating signals along the lines of an analog meter.
Note: This meter is pre-owned. It has some scuffing as well as a small scratch on the bottom of the meter near the probe inputs. Otherwise meter is in great condition.
