VERNIER GO DIRECT NITRATE ION-SELECTIVE ELECTRODE
The Vernier Go Direct Nitrate Ion-Selective Electrode (ISE) can be used to measure the concentration of nitrate (NO3-) in aqueous samples. It connects via Bluetooth® wireless technology or wired via USB to your device.
Nitrate concentration, which can be increased by acidic rainfall, fertilizer runoff from fields and plant or animal decay or waste, is an important parameter in nearly all water quality studies. Vernier's Go Direct Nitrate Ion-Selective Electrode is used to wirelessly determine the concentration of the nitrate ion in a water sample. These levels can be measured as mV or mg/L.
The versatile BNC connector allows students to easily replace the electrode when it expires or becomes damaged. You need only replace the electrode and not the entire sensor—lowering your overall equipment costs.
The Vernier Go Direct Nitrate Ion-Selective Electrode has a combination-style, non-refillable, gel-filled electrode. Like all other PVC ISE membranes, the membrane on the ISE has a limited life expectancy. However, the replaceable module of ISE allows you to simply discard the used membrane module and replace it with a new one.
As this product has a finite shelf life we import it as required, allow 4 to 6 weeks for delivery from the date of your order.
COMPATIBILITY CHECK and Set Up Guide for your Vernier sensor, interface and software:
Rechargeable Battery — Ready When You Are
The Vernier Go Direct™ robust rechargeable battery offers long battery life and provides always-ready operation. Monitor battery life directly from Vernier's free Graphical Analysis™ 4 app Should the battery run low simply connect the sensor to the charging cable and keep on collecting — no interruptions or inconvenience to you or your students.
Wired or Wireless — The Flexibility to Choose
Vernier's Go Direct™ sensors connect directly to your mobile device, Chromebook or computer using Vernier's free Graphical Analysis™ 4 app. No additional equipment or software purchases are necessary. Go Direct sensors can be used wired via USB or wirelessly via Bluetooth allowing you to choose the solution best for your classroom or laboratory.
Note: We recommend that you do not purchase ISE replacement modules too far in advance of their expected time of use as degradation occurs while they are stored on the shelf.

WarrantyThis product is used in teaching these Australian Curriculum codes:
ACSBL019 - Biodiversity and the interconnectedness of life - Describing biodiversity - Ecosystems are diverse, composed of varied habitats and can be described in terms of their component species, species interactions and the abiotic factors that make up the environment
ACSBL021 - Biodiversity and the interconnectedness of life - Describing biodiversity - In addition to biotic factors, abiotic factors including climate and substrate can be used to and classify environments
ACSBL029 - Biodiversity and the interconnectedness of life - Ecosystem dynamics - Models of ecosystem interactions (for example, food webs, successional models) can be used to predict the impact of change and are based on interpretation of and extrapolation from sample data (for example, data derived from ecosystem surveying techniques
ACSCH030 - Chemical fundamentals - Properties and structure of materials - Ions are atoms or groups of atoms that are electrically charged due to an imbalance in the number of electrons and protons; ions are represented by formulae which include the number of constituent atoms and the charge of the ion (for example, O2–, SO42–)
ACSCH032 - Chemical fundamentals - Properties and structure of materials - The characteristic properties of metals (for example, malleability, thermal conductivity, electrical conductivity) are explained by modelling metallic bonding as a regular arrangement of positive ions (cations) made stable by electrostatic forces of attra
ACSCH031 - Chemical fundamentals - Properties and structure of materials - The properties of ionic compounds (for example, high melting point, brittleness, ability to conduct electricity when liquid or in solution) are explained by modelling ionic bonding as ions arranged in a crystalline lattice structure with forces of attract
ACSSU176 - Biological Sciences - Ecology - Ecosystems consist of communities of interdependent organisms and abiotic components of the environment; matter and energy flow through these systems
