ANALOG /DIGITAL DMM
Soar's 3200 Series 3-1 digit multimeters combine the features of a state-of-the-art digital multimeter with an analog bar graph display. The high-resolution 3200-count digital display delivers the resolution of much costlier 4-1/2 digit meters for measurements above 2,000 counts. The 32-segment bar graph display is ideal for readings that change-peaking, nulling and observing trends. These DMMs are simple to use. Just select your function with the handy 8-position rotary switch and test. The meter automatically selects the range with the greatest accuracy and resolution. The function and measurement range are even shown on the LCD
The SA-600 offers a safe 20V handpiece with a 65W heating element for excellent heat recovery and temperature stability.
The high mass desoldering nozzles provide superior heat capacity, allowing efficient solder flow at lower temperatures. Featuring vacuum and hot air blow functions, the SA-600 has a variable temperature range of 660° F (350° C) to 840° F (450° C). display. Touching the RANGE button on Models 3220 and 3230 prevents the instrument from changing ranges, which saves time for repetitive go /no-go checks. Both models also have an audible continuity feature which causes the meter to beep when the circuit under test is closed. After pressing the DATA-H button on Model 3230, the meter captures the measurement, beeps, and locks it on the display so you can focus your attention on the probes and circuit. With this data hold feature, the DMM automatically updates for each new measurement. All 3200 Series multimeters come with safety test leads, operator's manual, batteries, spare fuse, and 3-year warranty. And each meter is priced under $100. For further details write or call: HMC Co. P.O. Box #526, Canton, MA 02021 (617) 821-1870.

PROGRAMMABLE SOLDERING STATION
From Contact East a new programmable soldering station that has a tamper-proof temperature setting, quick heat up, and increased thermal recovery permitting consistent, high quality soldering, with less dwell time on multilayered boards and heavy ground planes. Temperature can be set on the digital key pad, from 400° to 899° F, with an accuracy of +/- 0.9° F. Once the temperature is set, unauthorized personnel cannot change the setting without the programming card. The temperature memory system allows the iron to be shut off and turned on without having to reset the iron each time. The housing, iron and cord are made of static dissipative material-ideal for static-safe areas. Resistance to ground is less than 2 ohms, and leak voltage is less than 0.6mV. Priced at $299.00, hobbyists may find the cost a little steep for their workbench but for the hobbyist who has everything, this has to be the ultimate in soldering iron stations.
The station comes complete with iron-holder, sponge, programming card, 50W iron (with A1016 tip) and operates on a 115VAC (3 wire cord). For additional details and /or information, write or call Contact East, 335 Willow Street, North Andover, MA 01845 (508) 682-2000.

DIGITAL DECADE SUBSTITUTERS
Substitution boxes are economical, indispensable tools used in a variety of engineering, design, troubleshooting and service applications. With convenient side-by-side thumbwheel switches, you can easily dial in the desired resistance, capacitance or inductance value.
These substitution boxes are used to set resistance, capacitance and inductance values for engineering, design, troubleshooting and service applications.
Just dial in the desired value using convenient side-by-side thumb wheel switches-no fumbling with multiple slide or rotary switches. Different colored switches separate the various impedance ranges. Since the impedance values are set and read directly, no mistakes can be made as with rotary or slide switch decade boxes. There's no need to examine groups of switches-simply read one number. Made of high impact plastic, these substituters are very portable and reduce clutter on a busy lab bench.
Four series of substitution boxes are available: RS Series sets resistance; CS Series sets capacitance; RCS Series sets both resistance and capacitance; and LS Series sets inductance. For details contact: HMC, P.O. Box 526, Canton, MA 02021-(617) 821-1870
