  • Making accurate pH measurements

    In this article, we will tie the analogy of. accurate time to pH measurement and show how to make more accurate,. dependable and believable pH measurements by using three pH sensors.

  • pH Meters and ORP Meters

    pH meters and ORP meters are used to measure or monitor potential of hydrogen (pH) and oxidation-reduction potential (ORP). pH is the negative logarithm of the hydrogen ion activity in solution. The pH value of a substance is directly related to the ratio of the hydrogen ion [H+] and the hydroxyl

  • pH Tech Tips (.pdf)

    The Concentration ratio of hydrogen ions (H+) and hydroxyl ions (OH-) determine the pH value of a solution. Any hydrogen activity will produce a 59.16 mV/ pH unit across the glass membrane. The measurement is expressed on a scale of 0.0 to 14.0. Water with a pH of 7 is considered neutral (H+ ions

  • Carbon Dioxide for pH Control

    is safe to handle, easy to apply, efficient and ecologically safe. When pH control is critical to your process or effluent quality, CO2 can be a most viable alternative.

  • The pH Factor: Why Measure (.pdf)

    Often, the first question asked regarding measurement and control of pH is "What exactly is pH anyhow?" The "p" in pH is actually a mathematical symbol for the negative logarithm, and the "H" represents the element Hydrogen.

  • Guide to Minimizing User Errors in pH Measurements

    Over one hundred different compositions available from many different manufacturers None exhibit completely linear pH response in overall pH range specified Maximum available pH range: -2 to 16 pH in aqueous solutions Optimum, linear pH range: typically 2 pH units less specified minimum and maximum

  • Re: Elevator control circuit

    I need a schematic diagram of a 5-floor elevator, please help me sir! my email add is ajmguinahan@yahoo.com.ph...

  • Re: PA Mixer/Amp PCB Schematic

    My son is constantly tearing down and repairing mixers, amps, and whatever. He hardly ever replaces entire boards but sometimes it is necessary. No reason you can't just replace the capacitors if you can identify them. If not try searching online for places that sell the schematics. perhaps thi...

  • Re: Single Phase 240 Volts to 3 Phase 240 Volts

    Here you go. Miller 3 ph converter design. All you need to know about making a good reliable and stable phase converter of your own. I am the same guy there as here so I know the design works well!

  • Re: Converting 3 Phase to 1 Phase in Reverse?

    Thanks for the PM you sent me. I will try and work up some better details as I have time. Fist thingiI would suggest is looking fore schematics for 9 lead and 12 lead dual voltage three phase motors then read up on what a zig zag or 'Z" connection is regarding getting single phase form three phase.

  • Dover Elevator - Hydraulic Pump Shuts Off

    I have a Dover elevator single story 480 3 ph. On energizing, the hydraulic pump runs for about a minute and then shuts off. I have very limited schematics but I do see a pit safety switch in series with a power supply that could keep everything from working. Nothing is working but I have good power...

913 pH Meter

The 913 pH Meter is an easy-to-use measuring instrument for routine operation in the laboratory and on the road. pH or mV and temperature can be measured in parallel with one analog and one intelligent sensor and output to a large colour display. Important information such as charge state, quality of the calibration, calibration interval, etc. can also be clearly viewed at a glance. A PIN-protected expert mode protects the instrument against unintentional changes of different parameters...

Hach Company
pH Ultra Probe

Hach's pH Ultra Probe has the fastest stabilization, even in difficult measurement samples. There is also no need to question if the probe has stabilized, because it locks in as soon as stabilization is complete. Try an online demo and see how this feature can help you. HQd ™ meters and probes are a customized solution for water quality testing. Designed specifically for water applications, the probes are available in a wide variety of parameters. They are compatible and fully...
