Brothers and Sisters- A couple of weeks ago there was a thread about pH meters. I found one in a catalog today that looks pretty good. The Pocket pH tester- range 0.01 to 14.0 +/- 0.2 accuracy. 2 point calibration, fast & easy. LCD display. The thing looks like a pocket LCD thermometer. Also has replacement electrodes available. I forgot to write down the cost, but think it was 44.95, and replacement electrodes were 9.99. In the catalog of Lab Safety Supply, Box 1368, Janesville Wi 53547-1368 Order 1-800-356-0783 Technical 1-800-356-2501 Tester is item # 9X-25572 Electrode is item # 9X-25573 Usual disclaimers. I have done business with these people and they are friendly and fast. The gabacho chile picker and firm believer that a person can't have too many tools <<<boz>>>
