PH60 Premium pH Tester by Apera

The Apera Instruments PH60 Tester is the new generation premium pH tester for all kinds of regular aqueous solution's testing, such as hydroponics, aquaculture, pools & spas, water treatment, cooling towers, etc. Features ACCURATE, QUICK & RELIABLE measurements. Besides the regular glass bulb probe, there are 3 other types of replaceable probes for your choice to meet your specific testing needs.

Up to 3 points (4.00, 7.00, 10.01) of Auto Calibration with auto buffer recognition and 0 to 50°C Auto Temperature Compensation (ATC), ±0.01 pH, 0.5°C accuracy with -2.00 to 16.00 pH measuring range, auto recognition and reminders of stable values improves consistency, saving you the trouble of guessing when to manually hold measurement (auto hold function available).

Equipped with a large clear LCD with 3 backlit color (blue for measuring mode, green for calibration mode, red for heads-up), it supports dual display of temp./pH value and indications of completed calibrations (where L/M/H indicate 3 points of calibrations) and stable readings (with a smiley face).

Unique High/Low Value Heads-Up function: the screen will turn red if measurement is higher/lower than a preset value, instantly reminding you of any results that need your attention.

Great value---Comes with a complete kit of premixed calibration solutions (4.00 and 7.00), soaking solutions (3M KCL), calibration bottles, AAA batteries, and a lanyard all in a portable carrying case.

Easy menu setting, customizing your tester's functions according to your needs. Smart self-diagnosis, warning of out-of-range measurement and incorrect calibrations. IP67 waterproof and dustproof, floating on water so you don't have to worry if it falls into water by accident. 2000 hours' continuous operation (without backlit) powered by AAA batteries (with low power warning and auto power off in 8 min if no operation).

The meter is CE certified and comes with a 2-YEAR Warranty (6 months for the probe). The company designs and manufactures scientific analytical instruments like meters and sensors for pH, conductivity, turbidity, and dissolved oxygen for over 25 years, and meets ISO 9001:2008 Standards.

WD-35641-51 Double-junction, Epoxy-body, Polymer Gel-filled pH Electrode (Use with all OAKTON pH meters except pH Wand and pH/CON 10) by Oakton

Use with any meter with a BNC connector

Choose a single junction electrode for field, clean water, and general purpose applications. Choose a double junction electrode for most applications, including dirty water, heavy metals and organics applications.

All electrodes have a BNC connector, and are 12 mm dia with a 3 ft cable (except submersible electrode, which is 25 mm dia with a 10 ft cable). We offer many other pH and ORP electrodes for specialty applications.

• Each 12 mm electrode includes a FREE electrode saver bottle to extend electrode life
• Use ORP electrodes with meters that read mV to take REDOX readings

1295-0222 Chemcassette Tape, Hydrogen Cyanide (monitors up to 16 days) by Honeywell Analytics

Chemcassette® is the unique trademarked name for a calibration free toxic gas detection method that uses an optical scanning system to detect the presence of gas by a colour change on the specially chemically impregnated paper tape. Chemcassette® technology is highly specific and reacts extremely fast to the presence of parts per billion (ppb) levels of many hazardous gases. Over 200,000 points of gas detection are currently maintained by the Chemcassette® sensing technology at any given time around the World in some of the most critical safety applications possible.

Each Chemcassette® is manufactured to traceable ISO 9000 manufacturing standards by a world class team of highly trained chemists and each batch is calibrated with ultra pure gas that is traceable to nationally accepted standards. This means that the end user does not have to provide calibration facilities themselves thereby saving cost and reducing risks to their own staff.

Efficient high volume manufacturing techniques means that there is always available Chemcassette® in stock that can be shipped anywhere in the World so that our customers are never left without adequate safety cover. Application support with expert gas detection chemists is available by phone and e-mail and is supported with many years of technical application notes and help to diagnose common support issues.

Should there be any concern regarding the performance of an individual Chemcassette®, a free of charge evaluation will be performed to trouble shoot the observed scenario using the award winning quality management system "Customer Discrepancy Report" CDR. Every CDR completed by a customer is guaranteed a full response and the outcome is reported directly back to the end user to ensure a complete resolution process.

Each Chemcassette® is backed with a full warranty and we have over 20 years of experience regarding the quality control of our proven sensing technology.

Additional Features and Benefits:

• Visible proof of a gas release event
• Greater sensitivity (detection down to parts per billion levels)
• Superior selectivity (less cross-interference with other gases)
• Fast response time
• Low false alarm occurrence
• Stability (consistent, repeatable operation)
• No calibration required
• Easy to use
• Available in fixed and portable instrumentation
