SP-700 Water Multimeter
The Pyxis SP-700 handheld multimeter measures six key water treatment parameters simultaneously: pH, conductivity, PTSA, fluorescein, ORP, and temperature. Featuring simple, one-handed operation, the multimeter leverages Pyxis proprietary technology combining electrochemical and optical measurements in a cuvette-less platform.
With the SP-700, you can view results in under a minute for all key parameters for a typical water treatment application such as cooling tower analysis. The multimeter logs a complete measurement history, which you can transfer via Bluetooth to your smart phone or PC for statistical analysis.
Custom product names and tracer/product ratios can be configured via Bluetooth-enabled devices.
For highest accuracy, the PTSA measurement uses our proprietary signal processing algorithms to compensate for sample color and turbidity conditions, which would otherwise cause erroneous readings.
SP-700 Features
- Breakthrough technology combines PTSA / fluorescein with conductivity / pH and ORP in a single, rugged one-handed meter.
- Proprietary pH / ORP module design with extra-large junction capacity provides increased service life and can be replaced without opening the meter enclosure.
- Intelligent sensor aging and pollution detection capability provides self-diagnosis during calibration.
- On-board storage lets you record up to 8 Gb of historical data with time stamp and options to set up sample location information.
- Long battery life enables 10,000+ readings.

ST-500 Series Inline Fluorometers
The popular ST-500 inline fluorometer is a robust and highly accurate tool for real-time monitoring of inhibitor dose. It is often used for feedback control to maintain dosed concentration within a narrow band around the set point, regardless of changes in cycle or heat load dynamics.
Now the ST-500 series includes expanded measurement targets for a broad range of analytes, including fluorescein and naphthenic disulfonic acid (NDSA), and brings its proven record of reliability to your traced cooling programs for boiler and other applications.
Thanks to its state-of-the-art fluorescence technology, the ST-500 Series handles a wide range of real-world sample water conditions. With its flow-through optical design and multiple wavelength color-turbidity compensation algorithm, the ST-500 probe maintains high performance for water samples with up to 100 NTU turbidity and/or 5 ppm iron.
The competitive probe comparison shown in the experiment below clearly demonstrates the superior performance of the ST-500 probe in the presence of iron color.
Typical Applications
- Traced cooling water treatment programs
- Traced boiler water treatment programs
Features
- Color and turbidity compensation for accurate readings, long-term stability, and less frequent calibration.
- Typical maintenance cycle in months, not weeks or days.
- Works with WiFi and Bluetooth adapters for one-press calibration with the SP-910, 700, and 400 tools, and for firmware upgrades via your smart phone.
- Isolated 4-20mA output: no need for additional transmitter for easy connection with PLC and DCS.

ST-700 Inline pH / ORP / Conductivity Sensor With Embedded Transducers
The Pyxis ST-700 series of pH, ORP, and conductivity probes are designed to simplify installation, calibration, and in-use operation in industrial wastewater and cooling water applications. These probes have an embedded 4~20mA transmitter.
The oversized platinum disk ORP and the flat pH bubble sensing elements increase resistance to contamination. The double salt bridge design with large junction capacity ensures a long sensor life with minimum maintenance.
Typical Applications
Industrial wastewater treatment, cooling water treatment
Features
- Dual embedded transmitters in sensor housing: 4-20mA and RS-485 supporting MODBUS.
- Large conjunction capacity (compared to replaceable electrode design) leading to longer service life.
- Longer maintenance cycles with high contamination resistance. Eliminates the need of pre-amplifier and transfer signal directly in 4~20mA or digital protocol.
- Enhanced robustness when controller is away from sample point.
- Specially designed pH/ORP electrodes tolerant to short time frozen during shipment or storage.
- Stainless steel solution grounding point on sensor to stay away from ground loop problems.

Blacoh
Valve Hybride – Blacoh
l'avenir des systèmes de pompes doseuses. Présentation du premier amortisseur de pulsations combiné au monde et soupape de pression noire.
La nouvelle Hybrid Valve ™ de Blacoh, en attente de brevet, associe le contrôle constant du débit d'un amortisseur de pulsations et la régulation d'une vanne de contre-pression pour fournir les performances et les fonctionnalités des deux. Pourquoi installer et entretenir deux équipements lorsque le Hybrid Valve ™ fait la même chose, mais seulement mieux.
PERFORMANCE: LES CHIFFRES SONT INDÉNIABLE
La soupape hybride en instance de brevet a été conçue selon des principes éprouvés avec une conception de pointe pour des performances optimales et une efficacité maximale.
Dans un système de pompe doseuse, l'utilisation d'une soupape de contre-pression seule (orange) n'améliore en rien le débit de fluide. Lorsqu'il est mis en série avec un amortisseur de pulsations, le débit s'améliore de manière significative (rouge), mais les résultats ne peuvent toujours pas égaler les performances de la vanne hybride à construction unique pour le flux le plus stable (bleu).
Faites confiance aux experts en contrôle des fluides
L'emplacement et la proximité sont essentiels lors de l'installation d'amortisseurs de pulsations et de vannes de contre-pression dans tout système de pompage. Une soupape de surpression installée en série avec un amortisseur peut annuler l'effet d'amortissement si la soupape s'ouvre et se ferme avant que l'amortisseur ne puisse capter une impulsion complète. Cet effet d'ouverture rapide peut également générer trop de gain dans la soupape de contre-pression, ce qui entraîne une inefficacité et des bruits de claquement.
En combinant l’amortisseur et la soupape de surpression dans une seule unité technique, nous avons éliminé les problèmes les plus courants liés à l’installation pour un système plus efficace et simplifié.
VOIR LE HYBRIDE EN ACTION
Regardez notre directeur de l'ingénierie David McComb démontrer la Hybrid Valve ™ avec une pompe doseuse.
Il vous guidera à travers les performances de la pompe avec un amortisseur de pulsations seul, puis en série avec une soupape de contre-pression et enfin avec la nouvelle Hybrid Valve ™.
Comprendre les principes de la dynamique des fluides pour voir pourquoi la Hybrid Valve ™ offre les meilleures performances et donne à votre système la protection qu'il mérite.
