HX8 GrowNET 8-Port Hub by Agrowtek

Expand the number of GrowNET™ ports on your Agrowtek GrowNET™ digital serial bus network. Connect multiple GrowNET™ devices to a GrowNET™ master device such as an LX1 USB AgrowLINK™ for PC or LX2 MODBUS ModLINK for PLC applications.

Buffered hub extends the range of bus networks and can provide power to devices from the DC power jack. Includes eight ports for connecting devices and one port for connecting to the upstream bus.

Hubs may be daisy-chained as required up to the maximum number of ports on a bus (247 modbus/250 GrowNET™.)

Features

• 8 GrowNET™ ports for devices sensors, relays, pumps, etc.
• Provide power to sensors & relays from the hub ports
• Buffered ports for signal strength
• 1-Year Warranty
• Tough ABS plastic enclosure
• Made in USA

AI3151 LabSen 241-3SP Glass-body Micro pH Electrode for Micro-Volume Solutions Containing Proteins by Apera

Backed by proprietary Swiss sensor technology and premium materials, LabSen 241-3SP Glass Micro pH Electrode is designed for micro-volume samples (≥30 microliters) containing proteins such as serum and microbiological samples. With the ultra-micro container (sold separately), it can test as low as 15 microliters.

Unique Glass Membrane – LabSen 241-3SP pH electrode adopts a micro cylindrical sensor tip (top end ø3mm, stainless steel ø4mm), making micro-sample pH testing easier than ever, and can be tested in high-temperature samples (up to 212°F). The stainless steel protective shaft ø4mm) ensures the durability of the slim glass tube.

Protelyte electrolyte – A specialized oily reference solution made for protein solutions and viscous samples.

Long-Life Reference System - composed of a glass tube, AgCl, and a reference silver wire. The top end of the slim glass tube is stuffed with cotton, which prevents the reaction between AgCl and electrolyte when the temperature changes. It improves the stability of the reference system and extends the electrode's service life.

The electrode uses a BNC connector, compatible with any pH meters that use BNC connectors. No temperature sensor is built-in. Users need to have a separate temperature probe (ex: Apera Instruments MP500) to enable ATC or manually input temperature to achieve temperature compensation.

AI3155 LabSen 851-S Glass-body pH Electrode for Highly Viscous Solutions by Apera

LabSen 851-S pH electrode is designed for high-accuracy pH measurement of highly viscous samples such as coatings, syrups, resin, glue, and etc.

The pre-pressurized structure allows the electrolyte to stably flow out even in highly viscous samples so as to ensure reliable measurements.

LabSen S-type glass membrane - fast response and is 10 times stronger than traditional glass membranes, saving the electrode from accidental damage.

The electrode uses a BNC connector, compatible with any pH meters that use BNC connectors. No temperature sensor is built-in. Users need to have a separate temperature probe (ex: Apera MP500) to enable ATC or manually input temperature to realize temperature compensation.

• Proprietary sensor technology and premium materials from Switzerland
• The low-impedance S membrane ensures a fast response and is yet impact resistant.
• Pre-pressurized reference system for smooth electrolyte flow
• Silver Ion Trap Reference System ensures a stable reference potential and long service life.
• Lead-free glass body
