0572 2032 Saveris 2-T2 WiFi Data Logger by Testo

The testo Saveris 2 WiFi data logger system is the modern solution for monitoring temperature and humidity values as well as CO₂ concentration in storerooms and work rooms.

Installing the system is child's play, and can be carried out either via a browser, or with the testo Saveris 2 App. The WiFi data loggers reliably record temperature, humidity and CO₂ concentration at adjustable intervals and transmit the measurement values directly by wireless LAN to the Testo Cloud.

The readings stored can be analyzed at any time, anywhere, using an internet-enabled smartphone, tablet or PC. Limit value violations are immediately reported by e-mail, optionally by SMS or via the testo Saveris 2 App as a push notification. This allows critical processes to be kept always under control, even if you are not on site.

The long battery life additionally ensures that the testo Saveris 2 system needs to be serviced only rarely.

• Data transfer by wireless LAN
• All measurement data always available, anywhere, on any instrument
• Alarms when limit values are violated
• With testo Saveris 2 App for easier configuration, push alarms and WiFi range analysis
• Cost-free online data store (Testo Cloud)

1295-0225 Chemcassette Tape, Mineral Acids 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.

S354CDHF pH Sensor, Flat, Polymer, 12mm, HF, S8 by Sensorex

The specification sheet serves as an addendum to the pH LabSpecs sheet and covers all lab pH electrodes suitable for use in hydrofluoric acid.

Specifications differences for use in hydrofluoric acid (HF) are shown in SPECIFICATIONS section below. Please note 2 major differences as compared to standard electrodes. First, pH range is 0-12 not 0-14. Second, the temperature range is 0-50 deg C.

This series of electrodes are compatible with any lab or portable pH meter. Calibration of these electrodes is as normal with any standard pH electrode using standard pH buffer solutions.

• Resist attack and etching from HF (up to 2% v/v)
• Resist coating and fouling
• Compatible with any pH meter
