Fluke 27 Handheld Multimeter for sale: I paid $260 for it and will take the best offer around $200. I am selling it to buy an ultrasonic cleaner so I will consider some trading arrangement for an ultrasonic cleaner with a tank >= 3/4 gallon (and preferably a heater and timer). DESCRIPTION: easy to use rotary dial both fast auto-ranging and manual ranging min/max, relative, and touch hold features Audible continuity/Diode test This multimeter is tough enough to work anywhere - in the dirtiest, grimiest, or roughest jobs. Drop it. Overload it. Expose it to extreme temperatures (storage: -55 to 80 degrees centigrade, operation -15 to 55 degrees centigrade), high humidity, chemicals and contaminants (oil, kerosene, diesel fuel, gasoline, isopropyl alcohol, hydrochloric acid... ). It is a totally sealed multimeter with a separately sealed battery compartment so batteries can be changed without compromising the primary case seal. It is cased in polycarbonate/polyester alloy (used in car bumpers) and all components are shock mounted so it can withstand shock, vibration ,and impact, especially at cold temperatures. It is extensively overload protected and in most cases rather than requiring fuse replacement the meter displays "OL" without damaging the internal circuitry. The meter has a 31 segment analog bar graph allowing testing of erratic or changing signals and making quick dynamic measurements such as peaking, nulling, zero adjustment, or capacitor testing. The graph is updated 10 times faster than the digital display. The meter also stores the highest (max) and lowest (min) readings, allowing monitoring of a signal for seconds hours, or days. The relative mode remembers a reading and shows the difference between it and following readings. Touch hold automatically memorizes a stabilized reading so the display can be viewed after the measurement is made.
