THE OLIN MERCURY M O N I T O R FOR LIQUIDS Continuous and automatic measurement of mercury

concentrations in waterand aqueous systemsevery 6 minutes.

The Mercury M o n i t o r can analyze, detect, measure and record traces of mercury (in any of its forms) ranging f r o m zero to 5 p p m . A n d it does it all instantly. A u t o ­ matically. A r o u n d the clock. W e developed it for use in our o w n plants. Where w e don't want the p r o b l e m of momentary discharges of mercury. The M o n i t o r operates w i t h ex­ tremely high accuracy. It is so efficient, in fact, that it can't be fooled by organic compounds and sulfides that might be present in the sample. The M o n i t o r is ruggedly construct­ ed, designed for easy maintenance and requires no personnel to operate. W e perfected it to help us. It works great. Take it f r o m us.

Heath/Schlumberger's new Com­ puter Interface brings the inside of your PDP-8 out­ side to the real world

The new EU 801Ε Mini-Computer Interface allows owners of any PDP-8 family computer (with positive I/O bus) to take full advantage of their mini's capabilities...by allowing direct input of measurement data and output of processed data and control information. The 801E is ideal for interfacing a variety of digital instruments...designing complex dedi­ cated interfaces...or just learning about interfacing. All connection points necessary for a functioning interface are readily available outside the computer: all signals required for any given data transfer operation are legibly and logically presented on the top of a plug-in card in the 801E ADD unit. Connection points on the card top include 12-bit digital inputs and outputs (Accumulator In, Accumulator Out and Buffered Mem­ ory Bus), three control lines, five timing lines and two status lines. And because the 801E is a patch system using positive-contact connectors and ordinary hook-up wire, there is no soldering. Simple data transfer circuits can be patched and tested in a few minutes. Signal modifica­ tion and device control circuits can be quickly developed and refined. For detailed information on the new Heath/Schlumberger EU-801E MiniComputer Interface, send coupon below for free brochure...and learn how you can turn your PDP-8 into a maxi-mini.

Heath/Schlumberger Scientific Instruments Department 511-014. Benton Harbor, Michigan 49022 I'm convinced and t need a maxi-mini now. Enclosed is $ plus shipping for EU-801E(s). I'm interested but not convinced. Please send EU-801E brochure. Please send 1972 Instrumentation Catalog.

No heating elements . . . no electrical controls . . . 1 0 0 % proportional performance. Air movement generates heat . . . with no hot spots, no cold ones. N o point in this oven can exceed the in­ dicated air temperature. Temperature rises simulta­ neously in all portions of the chamber. Heated envi­ ronment inside the work chamber unaffected by external conditions. Ideal for hazardous applications, life-testing and other exacting work.

If you need a safe oven, send for this brochure. Write: Blue M Engineering Company, A Division of Blue M Electric Company; Corporate Headquarters: Blue Is­ land, Illinois 60406.
